Texture Packs Not Saving When Loading Up Game After Closing Game.

 Texture Packs Not Saving When Loading Up Game After Closing Game. Forcing Me To Reactivate Texture Packs every time. It is really annoying to have to go and re-click my texture packs every time I open Minecraft because it is not saving when I close the game. So please fix this bug asap! I updated to 1.1.28.0 and it has only just begun doing this since the update!
