Oh yes, I'm aware of this and I've been meaning to fix it, sorry. I'm actually surprised nobody has mentioned this before. Luckily I didn't make this mistake with my other asset packs. I'll fix it today or tomorrow and let you know when the pack is updated.
Oh you were not being rude at all! I appreciate that you mentioned it, thanks! And thanks for the compliments, I'm really glad you like my animations.
It's great that you could fix the positioning yourself, but I went ahead and fixed this asset pack anyway for everyone else.
All spritesheet frames and gifs are now 40x40 pixels and it should be a lot less hassle to use them now.
