[W:0.6.532] Bug/Exploit: Crashed ship part defenders can't spawn without room

[RemingtonRyder]

So, basically if you have something to wall the crashed ship part in with, the defenders won't spawn normally when you attack it.

There's only a slim chance of this being a viable tactic in unmodded Rimworld, because mortars (which are the only indirect fire weapons you could use to damage the ship) fire very slowly and aren't very precise.  I put an embrasure on one tile so that it was possible to fire in.
