Encountered a bug with the Dancer thrall. After he finished his, er, shift, we pulled him from, er, rotation and were able to place him nearby, where he began to do his thing and dance away. Merely being near one clears some sort of corruption debuff. To move the thrall, you literally walk up to them and hit E to pick him or her up. Really weird. Anyway, apparently there is a known bug with Dancers, and it's not a good idea to put them down more than once, or something, and this one abruptly turned into a "bad entry" and now we're going to have to head back down the river to claim another one.
