Enemy Sprite malfunction?

Have you edited their molds in FF3usME? Like a 128x128 monster will take a big mold and a 32 x32 monster will fit in a small mold. You can play with those in the formation editor in FF3usME. There isn't a combination for everything though, like you can't fit 2 monsters that are more than 64 x64 together on the same formation without have one deformed. If it's not the mold it could be the pointers but I doubt it. Try different combinations but you see the outline of the molds in the editor. The is a checkbox you need to click to see the molds...
