Couple things,

I was just playing my thief, who has a pinkish aura and when I went to the clinic to tick, all the doctors attacked me. Are they aggro evil or something???

Also, while I was playing my thief, it flashed that my vamp's unique item, cloak of the vmapire broke, even though that char wasn't even logged on. Can something please be done about this?

Thanks

Unique items are designed to decay when you are not logged on. Otherwise someone would grab a unique item and never log on, and nobody could get it. Some decay after X days logged off, some decay after X days logged on or off.

You'd have to a post a log about the doctors including the aggro message to see if it's a bug or not.
