I've seen a post reporting the trickster bugs maybe a week ago on the official forums. Same with gold dragon, still bugged. Game being playable doesn't mean that all the paths are working as intented.
Are these bugs game crashing? I don't think so. Sure, it would be better if the game runned perfectly from the day of release but I don't think it's a big deal if a few bugs are still a few bugsin game. If PF:KM tells us anything is that the game will work perfectly eventually, and PF:KM was way more buggy on release (that bear... XD)
