How to reproproduce it:

1. Install an old bepinex version inside modmanager
2. update bepinex version
3. it did not remove the old folder but creates a new one
   

How my plugins folder looks like after these steps
plugins.zip

Tried download old timberapi version and then update it and did not create any duplicate folders

BepInEx is no longer required. This is obsolete.
