When going through the checklist for 3.5, I added the achievements to the code for the Steam version of the game. But I never uncommented them in the code. It's not a big issues. If you want the achievements, replaying through Episode 3.5 should give you them. Most of you should have a save from Episode 3 in the autosave given how short the 3.5 was. There's also a variable snuck in there as well.
I've also changed the define code for Renee's character from 're' to 'ren' as 're' was conflicting with RegEx. Shouldn't cause any conflicts unless you happen to save on Renee's dialogue line in Episode 1. Which should be fixed with rolling back a bit.
Sorry for the all the little bugs in this update, and thanks for putting up with them! I'll be trying to limit them in all future updates! :)
So, the short of it is that you'll need to replay 3.5 from an Episode 3 save. If you're just starting the game, it should be fine. Sorry for the inconvenience. For those that don't want to replay 3.5, I'll be adding them at the beginning of Episode 4 as well. Just to give some choice. :)
This only applies to Steam, obviously. If you're playing a version from anywhere else (e.g. Patreon), then this isn't for you.
