Summary0011925: Crash guaranteed
DescriptionSomething occurs invariably within a small interval (maybe a point) of time that ultimately causes the game to crash (segmentation fault). I tried saving often thinking it was a random occurence, but in doing have only moved the save point really close to the crash event (making it really hard to try anything to fix it). I ran the game with gdb and the debug information (in the additional information) is at least consistent (the hex code in the last line was the same twice in a row).

Forgive me for being a gdb noob, but I just figured out how to print the whole stack. This is what the stack looks like when it crashes:

Most helpful would be to provide the save at some place like https://dffd.bay12games.com/category.php?id=20 [^]
