I applied the CoterieCraft resource pack in a world where I had multiple peoples' heads. The resource pack was for 1.7, and I immediately noticed that my own head had become that strange amalgamation of Steve that happens when applying a 1.7 skin to a 1.8 skin size. I immediately deactivated the resource pack, and my head stayed Steve. I deleted all of my SadGhoster87 heads, and gave myself a new one. Still Steve. Reloading, relogging, logging off and back on, nothing worked. The other people's heads stayed as their own, but my head stayed Steve.
Steps to recreate:
Apply a 1.7 resource pack in a 1.8 snapshot world containing player heads.

Player's custom head becomes Steve when resource pack is applied- and never changes back

There are new items that have been added to the snapshots for 1.8.
Resource packs won't work properly because they are made for previous versions, unless they are made specifically for the version you are playing on.
