If not, here's one that looks like a bug:
1) Open a Perk that has multiple Perk Entries (PlayerWerewolfFeed for example).
2) Add a new Perk Entry, or edit one of the existing entries.
This causes the Perk Entries to change their order for no apparent reason. Not a game greaking bug by any means, but pretty annoying when there are multiple identical entries in the list.
(This is a bug, right? I can't see any sense in this)
