Hello divers!
It's been a while, but over the past two years we've been taking bits of free time here and there to go back and improve this game where we can.
It's not perfect, but we've been able to resolve some of the major issues that were plaguing the Resubmerged edition, like quest breaks, save file issues, and inventory problems.

convert save file serialization to more stable format
fix a ton of little UI bugs
fix inventory overflow problem
add controller mapping for Dualshock 2, 3 gamepads
fix Xbox One gamepad recognition on Windows 10
fix various quest breaks and missing quest assets
enable 4:3 aspect ratio
We hope you enjoy diving back in to Diluvion! We have a Discord now if you'd like to chat with us, show your sub, or report an issue!
Thanks everyone, happy diving!

Save File Issues

Hello there!
Some players have had issues with data going missing from save files (items/gold disappearing, missing quests, etc), and if you're one of those players, this post is for you. Although we've attempted numerous times, we've been unable to reproduce this issue, which leads me to believe it's system specific. (not dissing your computer)
If you're having this issue and would like to help resolve it
We have a new development build on Beta branch- switch to the dev build and it will produce extra info that we can use to squash this bug. The best way for us to identify and fix it is to have an output log from a play session where it happened. If you do see error messages on screen during save/load, please send us your output log from the play session in the forums.
Steps to access the dev build:

In Steam, right click on Diluvion and select 'Properties'
In the properties window, select the 'BETAS' tab
In the dropdown, select 'beta'
In the 'LOCAL FILES' tab, click 'VERIFY INTEGRITY OF GAME FILES'
Confirm that the download begins
Accessing your output log

Make sure hidden folders are visible
Find the output log at C:\Users\username\AppData\LocalLow\Arachnid Games\Diluvion\output_log.txt Thanks again for anyone who is able to help!

Sub-aquatic adventure Diluvion: Resubmerged looks seaworthy after a major overhaul
Despite its exciting premise of Jules Verne-inspired nautical adventuring, sea monsters and mechanical leviathans, Diluvion sank out of sonar range shortly after launching early last year – yesterday, it resurfaced under an expanded name. While a striking looking game, it got dep

Hello again fellow divers!
Gamepad Controls
The latest version of the Diluvion 1.2 beta has been uploaded to beta branch, and it includes gamepad controls. There's some handy new features in this version, such as being able to use the bumpers to cycle between characters & stations.
So far we've tested with Xbox One / 360 controllers, so if anyone has other controllers they'd like to test with, it would be much appreciated!
Also, we've decided to go with Diluvion: Resubmerged for the official name of 1.2 Thanks to Thuzar for the suggestion!
Localization
Since there's new text in this version of the game, we'll be posting a new localization doc soon for community translations of additional languages. Since there's a significant cost to localization we will only be localizing the original launch languages ourselves. However, we'll gladly implement any languages that the community is able to localize.
Full Changelist

gamepad implementation
'Ghost of Morgensonne' quest revisions
hidden UI is still interactible - fixed
an empty iron minnow gets placed in players ship inventory - fixed
banquet hall shouldnt finish until you speak to athena - fixed
objective marked [none] displays when undocking from fountain of honor - fixed
Charles Spirios quest - implemented
on pirate bounty, the 'destroy first group' objective gets marked as complete automatically - fixed
Steel Hammer - implemented
fix positioning of sailors in stations so they never overlap officers
The Connoiseur - implemented
Naglfar hazards revised
Landmarks not appearing on compass - fixed
Sonar Guild quest - implemented
when torpedo module is removed, torpedo ammo HUD shows bolt ammo - fixed
when torpedo module first activated, the torpedo HUD doesn't get instantiated - fixed
fix positioning of item descriptor in loot panel
Added popup to explain Coolant tanks if you have no engine kits
Overdrive doesn't display "heating up" graphic after upgrade - fixed
Until next time!

Hey there! It's been quite some time since our last announcement. We have a new update to the beta, and this is a big one!
The beta's main quest line is now complete from start to finish.
We've fleshed out the Abyssal Trench quite a bit, and there's a lot of new stuff to see there.
Check out our update video here
We'd also like your input on what the full title should be: Right now it's between Diluvion: Accretion and Diluvion: Sunken Grimoire. Let us know in the comments!
Changelist

Completed quest chain in Sunken Coast
Completed quest chain in Abyssal Trench
Items can be used in hazard battles while salvaging
Completely revised quest update HUD
Added 'Crew Overview', 'Sub Overview' panels to Captain's Tools
Fixed Sonar bug where signals were never decaying
Fixed bug where AI would use player's ammo
Crew Exchange - crew can be placed on standby when swapping to a smaller ship
Fixed numerous small UI bugs
Revised munition effects
New scenes for forging an upgrade, swapping ships, upgrading chassis
What's Next
First on our todo list is to complete the script for the few remaining side quests so that we can begin full localization. While that's happening, we'll be working on gamepad implementation and general polish.
Thanks for reading, and we hope you enjoy the latest build. :)

1.2 Beta Updated with Save-Anywhere Feature
To all our players, thank you for sticking with us through this journey, and having patience with bugs and imbalance in the beta build. Your feedback not only helps us identify issues, but motivates us along the way. To new players: there are effectively two versions of the game
To all our players, thank you for sticking with us through this journey, and having patience with bugs and imbalance in the beta build. Your feedback not only helps us identify issues, but motivates us along the way.
To new players: there are effectively two versions of the game available. By default, you'll get the stable launch version. We identified some mechanics and features we want to change post-launch, so we created a newer version with the working title of 'Diluvion 1.2' (yes we're coming up with a better name). The new version is still in beta, but it's available to you if you're interested in being involved in the development process.
We've updated the beta with a much requested feature - as long as your sub isn't in immediate danger, you can save anywhere! We still have the 'save fish', which behave more like an autosave.
Full Changeset (1.2)

Added option to save in pause menu
Added option to load file in pause menu
Reworked 'load file' panel
Fixed bug where speed would increase indefinitely when changing helm station's crew
Fixed soft freeze when quitting to menu
Added confirmation panel when quitting to menu or desktop
Fixed bug where camera would lock when swapping ships
Lots of small hazard balance tweaks
Balanced loot values in Sunken Coast
Known Issues (1.2)
Torpedo targeting UI can be buggy
DLC ships will appear as an empty chassis - do not switch to this empty one
Some issues with the Lich hazards
