Filemon ? Is that a Pokémon critter ?

It's nigh certainly not an issue with the assorted text files anyway, as -show_err doesn't say anything and those would then turn up about all the time.

did you have that spritepack rcross? Or were you playing with just 0.74 and nothing else?
Now that you mention it, I'm pretty sure it's only started in my case after I put in the spritepack as well as some other stuff like the stratmap resources (plus the grass mod thingy). But I'll readily admit I don't have the foggiest how the sprites could be at fault so incoherently, and the new resource graphics would seem a tad far-fetched for a cause. You'd think that if there was some trouble with them it would turn up in some fashion in the stratmap itself, not when trying to load up to battlemap...

And then there's the thing it doesn't CTD all the time, just when loading battles after the first of the game session.
