In the last update I added encryption for skins and the resource will automatically clean up skins with broken links.
However, two problems arose.
A) False positives started happening with broken links and so valid skins were unfortunately removed as a result. This didn't affect all the skins but a good piece of them if you were in game yesterday. This is now fixed. Just re-upload if you find your skin was removed.
B) The encryption can cause split second lag for the client when it needs to apply a skin.
Right now I either have to decide to remove encryption all together or judge based on how bad the split second lag gets. I don't see it getting any better so it will probably end up getting removed, which means it was a big waste of time..
