hatches commit suicide with liquid bottler

Believe me....I have hated this but its not really a bug, the floor is drop downable iirc your dupes can also do it if they need down there for whatever reason... so many hatches lost to this

It's probably the same bug as the one that causes them to fall through pneumatic doors.

The bottler is not a proper obstacle, but "reports" as one for purposes of pathfinding. Dupes deal with it just fine, but hatches update more like items than actors and items fall through bottlers.
