Thanks for putting that in a spoiler. No errors, just a lot of warnings and I don't know if any of those are problem causers.
Which building are you referring to? The Lodge or the Arrow Forge?
EDIT: cleaner "cannot be found" errors are okay but you should only be seeing those if you haven't started the game since you last ran cleaner. If you start the game, quit, then run cleaner and it still says "not found" then there's something mighty strange going on.
