This is kinda serious, I can't swim in deep water anymore so I'm stuck in my tank in the middle of the ocean and there's a lot of stuck biters. Is there some way I can fix this?

Okay nvm I found a workaround. I downloaded version 0.5.2, because you mentioned in another thread that you removed the Deep Water setting in that version. As a result, I can move in deep water again. I'm sure the settings reset is because I'm loading an old save, rather than an actual issue with the mod, but if anyone encounters this again get version 0.5.2.

...double nvm, I just found out you can change startup settings on the main menu and it'll apply to old saves. All this time I thought it would only apply to brand new saves, and that once set for a save they couldn't be edited.
