When I turn on my resource packs sometimes it when i click done it will turn them all off instead of on. I've had this bugs in some 1.8 snapshots too but i don't remember which ones.

I've had this happen before. It seems to happen when the game doesn't have enough memory allocated to support the resource packs (e.g. 1GB for a 512x pack.) Allocate more memory to the client and the issue should resolve itself.
After having this issue:
Please attach the complete output of the "Development console" which can be found on the second tab of the launcher.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".
