OK, I see. Still a bit stupid that it's there only if you have the key but then that's not your fault - it's just awkward and confusing when trying to help other players! I've played through since about v.5 so did that event when it came out (hence, no key) so I didn't know if there was an issue that way as I just followed the hint to contact the janitor. I'm loaded (sorry, my fault Walkius won't be releasing an update this month) so there was no problem with the $50 and just thought that was the only route until somebody else pointed out there was an alternative option.
