Ok guys
Version 2.3.1 core 2.21 wowinterface module has been released.
Can everyone who posted in this thread about incorrect addon detections retest this ?
For each addon that was detected :
Make a back up of both your WTF and Interface folders
Attempt to update just that one addon through Minion (onion ?)
Watch the addons folder for changes.
If it's doing its job correctly it should install the latest version of that addon avaliable on Wowinterface. if not you'll see extra folders that aren't meant to be there !
Report back on your findings
