Which wiki?
I noticed someone had pasted some kind of erotic poetry into the middle of the goblins entry's description of sorcerors on the unofficial wiki. I didn't feel like making a wiki account to engage in an edit war with whoever did it, and it was kind of hilarious in an "in ur base, writing poetry on ur walls" kind of way.
I like the unofficial wiki better than the official one, it looks better, and has more information (such as about where items actually drop) - the only thing the official one seems to have going for it is stuff like pvp guides, which amount to "how to make your guy fit a cookie cutter template, and what traps have been invented."
Also, I noticed during a goblin invasion a little while ago that some of the goblins are apparently attempting to deconstruct closed doors, and failing to do it properly, resulting in duping doors (not that this is anything exploitable, aside from that they seem to stop trying to break in at this point, but you could have just built double doors to keep them out (except for the sorcerors)).
Summary:
Some goblins appear to try to deconstruct doors (others may just open them instead). What happens: It makes a deconstructed door (the kind you can put in your inventory and place on a tile), but doesn't actually remove the existing one. The goblins stop trying to break into it, though, until you open it. There's a visual glitch on the existing door after they do this, until you open it (an erased horizontal line of pixels in the center of the closed door).
