Was in the night market and was disconnected from the game for some sort of login authentication error. Didn't think much of it but logged back in.
The character I was on, and logged back into was a vampire, stage 4, all traits purchased.
As I was in the middle of The Parch I tried to vampire--run invisibly, but it wasn't working. Couldn't get it to work until I respec'd the last passive trait out, and rebought it.
Now, I'm in the "daring race" in The Parch, and I'm moving slowly as hell, when, as a vampire and nightblade, I scoot along really fast when crouching.
Not sure how it happened, but something is very very wrong with passive skills now. I really don't want to have to respec everything out and re-purchase it, which may include champion point allocations.
