The encounter with the hologram dragon in act 2 seems to be bugged. I'm getting the dragon every single night, after choosing to communicate and trade for info, then communicate and trade for shiny things, then just trading for shiny things (and losing reputation, arg).
edit: I also breathed fire at it the very first time it appeared, because I clicked the wrong thing. Then quit and continued the game to see if I could redo it. Don't know if that's what caused the bug.
