Perk unlocking the red line fills up in the reversed way.

At PC - LIVE branch not beta.

Unlock all perks until the outer corners and the outer corner perk will fill up reversed.

I've seen this happen in the right upper corner and the right lower corner. Don't know about the other sides.

Don't know how to explain better. Perhaps I can add a video later. This bug has been here for a while.
