Passages/Crashing
Yes, I know here I am in 2024 trying to beat OMD2 again after years away, but the game keeps crashing every time I play Passages. I've uninstalled and reinstalled the game and still crashes on that map. The shame of it is that it's a LONG and annoying map (looking at you, Sappers) and I'm usually well into it (wave 8 or 9, though once at wave 3) when it crashes. Is there any support left for this game?
Also, trying to jump to OMD3 for a fix doesn't work because my old saves are fully loaded on there, and I'd rather start from scratch which isn't an option on that one.
Yes, I'm whining.
