Hi! I have a question since you're the most experienced person when it comes to mods. I tried to remix the gen 5 follower mod and replace it with my own sprite. I made sure that the sprites matched the original too but it seems not to work. So then I tried to follow your instruction on these kind of mods but still. All I changed is the Icon,the normal Garchomp follower sprites and the xml file. Is there anything I'm doing wrong?
