Hello!
So, how is the hard crash issue going? I'm here because my game also gives me a hard crash. I'm using XP Ace and this tilemap.
Interestingly enough (?), it only happens in Windows 7/10. In my other PC (it has Windows XP), it doesn't happen. It seems to have something to do with map size or something, because the bigger the map is, the chance of getting a crash is higher.
Also my game has an autosave function every time you change map, so I get the crash, load the autosave, and go through the map with no problems.
The other interesting issue is that games run way faster on that Windows XP machine, even considering it has less RAM and an older CPU. But this is something that happens to me with vanilla VXAce so never mind.
Salut!
