Patch Notes for unstable update 0.8-unstable.1

Hi there prospectors,

Welcome to another unstable update which introduces a new planet called Tyr; a water world planet with archipelagos, requiring boat travel to get from one island to another. If you have any feedback on how you're finding travel across the seas, we'd love to hear any suggestions that you have.

Thanks as always for the invaluable feedback and bug reporting and we hope you enjoy playing this update.

⚠️Please note: This update is on Steam beta branch ttw_unstable - Work-in-progress version and may be unstable in places.
In the run up to promoting the latest unstable update to the default version of TerraTech Worlds, we want to improve the quality of the build by finding and fixing as many bugs as possible and refining how the game is balanced. To play the unstable: Right click TerraTech Worlds in your Steam library, then select the "Properties" option from the drop down list. Now select "Betas" and then select the "Beta Participation" drop down box. Select the "ttw_unstable - work-in-progress version" from the drop down list. Your game will now update, and you will be playing on the unstable branch. To send us your feedback and join the community: Join our discord server and select the unstable role via the #role-opt-in! channel. This will add you to the secret unstable channel where you can discuss your feedback/spoilers. *Remember to always back up your save games before switching to the unstable branch.*

A new planet, Tyr

Planet Tyr is unlocked when the tutorial on Nibiru has been completed.
A world where a vast majority of the surface is covered by water.
The various biomes are made up of groups of relatively small islands.
It's possible to build a bridge if islands are close to each other.
Islands that are further apart require the building of seafaring Techs.

Game balancing changes

Enemy respawn rate for normal difficulty has been reduced from 60 minutes to 25 minutes.
- This should make it easier to earn money by destroying enemy Techs and selling off scavenged blocks.
When playing with Tech Block Crafting, the price for buying the recipes for the 3 basic boat blocks has been reduced.
The crafting recipes for the 3 basic boat blocks have been reduced as well.
The force that the tides apply pushing a Tech from the sea towards the land has been halved.

Bug fixes

The following bug should now be fixed in this update:
- Planes in Creative mode are occasionally offset from their starting positions, causing some to be unexpectedly flipped.

Until next time, Prospectors!
