I have a number of alts. This is affecting one of my alts, and not my main.
The alt picked up a second class today - warden - and somehow his "thorny vines" and "charged chop" are reporting as maxed at level 3. I believe he's had similar issues with his primary class, but I can't verify this without finding a housemaid, and there's none near me right now. this does not affect all skills.
For what it's worth, my main is a warden, and the only unaffected warden skill is one my main hasn't trained. But it's a pet skill, so that may be the difference.
I'll add more when I have the alt near a housemaid, or level it again.
[Edit - the newb is now level 4 Wd. Charged chop and thorny vines still claim to be maxed (now level 4) but briar shield has no points in it. My main has trained briar shield, so it's not simple bleed-over from the main.]
[I found a housemaid - looks like something is auto-training some but not all skills on this alt. It's got 0 TP in its primary class, 1 skill MAX'd, and others at level -1. Something's wrong here. The question of course is: game bug, or berserk add-on? Good thing it's not messing up my main AFAIK. Any advice on turnging this off would be greatly appreciated.]
