Bugged passive tree, can allocate passives without points left to spend

My passive tree is bugged such that I can repeatedly allocate passive points in two sets of four without actually having any to spend. I don't receive any bonuses to my character from them, but the nodes allocated with the bug count as filled, meaning I can't allocate real points to those nodes. Removing the bugged points at the passive respec vendor costs gold like it would with real points, but doesn't add back to my available real points to spend, so there doesn't appear to be an infinite passives exploit as a result of this bug. I found that I could allocate the bugged points, exit and reenter the passive screen, then allocate another two sets of four bugged points from any other branch where I had spent real points, but could not follow a branch started by bugged points.

There may be some connection to my weapon specialization points, since I currently have four on my character, and the two sets of four bugged points are bordered a bit like weapon spec points, with one set being bordered in indigo and the other not bordered at all.

More bugs abound. I had left the bugged points allocated because I didn't want to spend the gold necessary to refund 8 points, but I soon discovered that I could no longer refund any points except the bugged ones. I earned the necessary gold and refunded the bugged points, and that problem has disappeared; I can no longer allocate bugged points.

Instead, my real points are bugged. After trying to allocate two new weapon spec points, one of the nodes I allocated consumed both a weapon specialization point and a standard passive point on the same node. I refunded the node and got both points back, and this time spent the standard passive first. It seemed to work as normal, but now I can't spend the second weapon specialization point, even though the game says I have one available to spend.

I’m having the same issue. I’m getting very confused which points are “real” and which are bugged.
