I haven’t heard of this happening. They’ve always placed any changed files in a backup folder. I manually updated to 235.8 this time though. Anyone else seeing this?
I wasn’t watching and haven’t looked to see if the launcher update made a back up since I made my own right when 235.7 was launched and never updated to that “broken” version. However all my files remained exactly the same as I left them other than the obvious test map wipe.
