Thanks for reporting. It's a weird issue I'm investigating. Has it happen again or just this once?
Didn't return after receiving this error. I was awaiting a patch.
I've just added a new patch with performance optimizations. Hopefully the game shouldn't crash anymore. But please let me know if it does for you
Nope, still crashed after completing the third stage. And game still doesn't autosave. Please fix autosave.
