[TB-247630] Hatches just passing through any doors

I think I get what you're saying, but I don't think this is a bug. It could be better explained in a "door tutorial" somewhere though. I had my own mishaps with them!

Anyway, doors aren't invisible barriers. Like a door in real life, if it's open, other stuff can come through it; i.e. hatches can also walk through a door if it is left open by your dupes.

The same goes for door permissions, too. If you set a door to have THRU RIGHT ONLY permissions, but also set the door to OPEN, your dupes *will* be able to go left through the door. As will any hatches, morbs, slicksters, pufts, etc...

If you want to make sure no hatches get in your base, you can 1) put up a couple more doors, 2) pen the hatches in somewhere that they would need a ladder to get out from, or 3) build a tile over wherever the hatch digs into the dirt to sleep for the night.

Hope that helped!
