Hello, I’m been making a mutation mod in the json files. When I got to making the sprites I used [Alternate ear graphics](https://github.com/Zupercharged/CDDA-Alternate-ear-graphics) and copied how they formated their overlay for mutations. Things were going well, until I made a new mutation for birds called iridescent feathers. ![bird](https://us1.discourse-cdn.com/flex016/uploads/cataclysmdda/original/2X/5/545a8bfe2a0151cff25b3228550ed056a37eb926.png)  
The beak was going under the feather and I could find out what changes the layer orders of the mutations so the feather goes under the beak like the one on the right which is the normal feather. I’m hoping that someone here might know how the layers for tile mutations works.

After making an entirely new mutation, with all new sprites, I found that when applying a new mutation the newest mutation’s sprite is placed below those of older mutations.  
 ![layers](https://us1.discourse-cdn.com/flex016/uploads/cataclysmdda/original/2X/6/6e0137b72011ac8f867ea7ad9eab018a7ec3e355.png)  
Example:

1. The ears are behind the body (fur) layer, while they are supposed to be in front. This is how it will load by default.
2. ~~This is how it’s supposed to look like, but this must be done manually, buy removing and reapplying the fur.~~ The tail in this one is over the fur.
3. All of the layers are behind the fur layer besides the ears and tail. Caused by removing and reapplying the fur, and then reloading.

Ok, this is 3 years old, but what do you mean by removing and reapplying fur? Newb here so i have next to no idea.
