I don't know how to reproduce this bug, but since I hit 80 (a week after launch) I've had infinate AV marks, perhaps someone might find how to work this one out. I haven't play'd AV since, because I don't want to lose this - so I haven't really been able to run any tests.
On another note, I also have an extra talent point at my Paladin, When leveling up I put full points in BoK, however after each game restart the first point in BoK resets, giving me one additional talent point to spend.
EDIT: I don't wish to bump this old thread, but the cache statement is incorrect, I do the "For Great Honor" every now and then without doing AV (haven't done AV since i got the bug). I would also like to add that, I don't have the paladin bug anymore, because I did a respec (I did however have one additional point to spend, not that there was anything useful to spend it on, but an additional point is till an additional point). Now, however, I have a free respec every time i relog the game (after I bought dual spec). Yes, the talents resets.
