As the title might imply, this is a pretty simple bug: Whenever the individual psychotic squirrel event occurs, there isn't a 'Go To Location' option available. This is in build 250, and upon further inspection it doesn't occur with boomrats. Muffalo have yet to be tested.
Was already on the bugtracker.
According to tynan it already should have been fixed
