Alrighty so that's never happened before? The cooking system has given some problems (I have build that should fix it but its on another hard drive and I'm searching for it). Were you putting in ingredients before clicking cook? In this build of the game, there's a missing error catch that means if you click "Cook" before adding ingredients it would crash the game. The menu lacked clarity so many people didn't realize that the highlighted boxes were for ingredients, so when I find the file I'll release it and it should fix the issue. I've edited it for clarity and added the catch but I still have to upload.
That COULD be why since that's a common problem in the game. That's my best guess but if not then I'll have to look into it further. It was my first time coding a system for anything and three days to do so wasn't enough so I sincerely apologize for the problems you encountered!
