The garage on the base doesn't fully close anymore. i think i remember it used to close completely on the old base and i saw it didn't close fully anymore a while back (there is a small gap between the garage door and the cement floor) but never mentioned it. It may be on purpose as it could give certain entities ways to get into your base or whatever, this could also be another reason to get rid of the hole in the ceiling of the garage. But i wasn't sure if anyone else realized this.
