ISSUE
Randomly, my server.dat file turns into a temp file. If I Re-covert it back into a server.dat It automatically turns back into a _tmp file sometime later. This makes it really frustrating as I have many servers added to my list. I have attempted to fully wipe out Minecraft from my PC and re-install, But that didn't make any change

@Galaxy_2Alex I have Deleted Optifine and completely re-installed the game, the issue still occurs. Please Help

Please also note that using third party modifications like Optifine can also cause issues like this.
