Whenever I open the Minecraft Launcher, it doesn't seem to save any of my installations (Optifine). And then when I open Minecraft: JE, it also doesn't seem to save any world saves, settings, or servers I was in. The launcher also re-downloads the game every time I open it. This has never happened before. An example of this would be: I launch my game, fix the settings to my liking, then close the game. I re-launch the game and the settings are switched back to default.
