Can we get them to stop changing clothes? Especially the dwarves! They are so white that it's disturbing to see them in nothing but pants.
Hello, I'm here from the apprentice protection society. We've had reports of abuse of some of our more drarven brethren. We're going to have to inspect your workshop to make sure everyone has good access to clothing and a sanitary work environment.
The issue with apprentices swapping clothes is one that has been going on from the start, but is so random that it is near-impossible to reliably reproduce and thus is nigh-impossible to fix. As near as I can tell, it happens when you have multiple apprentices and multiple uniform mannequins. Something about the loading process can change the appearance numbers based on which appearance loads first .. or something. :O (Yes, I've had it happen with my alt armies for years, but finding and fixing the error is another story.)
