That doesnt make any sense? As SPQR uses all the old sprites from 1.2 which didnt have the new animations from Alin, and I have experienced no crashes with them, and there are Several new animations that are totally different. Like teh doublehanded pike phalanx, and the Gladius animations. My understanding is the sprites would just use different animations than the 3D models since they are only 2D pictures anyway?

I think you might want to look deeper into it as you may have had corrupted sprite files or something, but I seriously doubt its the animations before making the sprites. Otehrwise I should be getting crashes alot as SPQR 5.0 didnt use all the new animations that 6.0 does, and I made ALL my sprites before the new 6.0 animation pack.
