Hi mate, I understand what you mean. The intent was to save file space, since Idle/Walk are usually smaller and don't need the extra space that attacks do. But I didn't know that would create problems when importing, I thought it'd just be a matter of choosing the correct frame size. I understand that centering all the sprites manually would require a lot of time.
I can't provide the .aseprite for now, sorry. You'd still have to manually rearrange all the sprites anyway, hehe, it's not just changing an export parameter. But I'll look into it as soon as able and update them.
Just to be sure, is it ok if different creatures have different frame sizes as long as their own animations are the same size? (For example, the Black Dragon needs much more space than others).
