in the piss maniac guild, if you piss against a specific spot behind the first toilet, the text freaks out and the piss upgrades just- stays there. You can just sit there and spam click the upgrade untill it stops responding, go out of the room, come back in, and do it again.
My piss level is 128 and it hits like a shotgun.
Oh also I've been having issues where some npcs don't have dialog, but I didn't know if that was intentional.
