Hey man, someone linked this thread in the technical issues thread I made about bugged/broken saves.
Freeze/Save problems The problem appears to be something bloating the save files/memory leak problems in fort joy, is it possible that we can fix an issue like that with your tool if we manage to identify the cause?
The problem is in levelcache files. Haven't had a problem in the first act (levelcahce of fortjoy was around 6 MB), in Reapers Coast when the save reached over 13 MB, boom, 4 minutes loading screen and crashing when loading in-game.
So you can easily extract the levelcache with this tool, and you can convert the file from binary to XML so you can edit it. The question is, how to reduce the bloating manually with that editing.
