MOVED: 7 Days to die always creates a new folder

Sounds like you've been using Vortex to install mods for 7 Days.

To fix it you will basically need to permamently delete the game client folder, probably the 7DaysToDie folder in your %appdata%, and definitely stop using Vortex for 7 Days. The hardlinks it creates can break client functionality, which causes the issue you are experiencing.
