I was prompted to give a bug report by the App and so I am doing as such.

I was going through the trainer back sprites and exporting them. I was exporting individually and in bulk to get a feel for how the tool worked. I'm not sure what even went wrong other than maybe exporting some of the sprites with the wrong pallet. (I hope this image copy paste embed works properly.

A separate or maybe related issue. If I do Export > All Table on the character back sprites some of them don't export but the ones that do export them all with the pallet of the currently selected character. In this case Wally.

Thanks for reporting! I've fixed it in the latest commit. It'll be working correctly in the next release.
