Issue Title: Agents taking cover in a corner near the door don't stun guards in melee reaction mode

Issue Description: When an agent is in melee reaction mode next to a door but there is a cover other than the wall next to that door, the agent often takes cover there and does not attack when someone passes through the door.

Kinda like this (| -- wall, # -- object, I -- door, ^ -- agent taking cover, @ -- guard).

|#

|^

I@

See screenshot.

If the agent in this particular case took cover as <, she would have stunned the guard.
