(I also use Yed_SideviewBattler to allow multiple frames)
For some reason, with an animated enemy's sprite the animations are shown at the top of the sprite, even if it's set to be shown in the middle of it.
With a non-animated enemy (default, single sprite), the animation will be shown in the right position.
The animation is set to play in the "Center" and it's coordinates are "0, 0":
There are no blank spaces between the frames of the animated slime sprite:
It may not look like a big thing since it's a small sprite, but the bigger the sprite, the worse it gets.
Repositioning the animations for the bigger sprites won't solve the problem, because then they will be shown in the wrong position with small sprites instead.
Making multiple animations is not practical either :|
