This morning I started running an Ace Chemical solo while I waited to que in to Trigon's Prison. I was doing the solo where you turn into a sludge monster. I was transformed into a sludge monster when the notification for TP popped up. I accepted it and zoned in. I stayed a sludge monster so we started the alert with 3 DPS's and a healer. I could not activate my armory and switch because I was transformed into a sludge monster. I could not remove the transformation because the shower was back at Ace Chemical. Other transformations are removed upon zoning and it appears that this one was missed. Unfortunately it did not appear that I recieved any benefits of the transformation either.
There are many broken parts of this game. Some may even say that there are more broken than fixed parts but that is a different post all together. I just haven't seen this specific issue discussed before. I wouldn't have cared except that I could use my armories until the transformation wore off.
