Issue Title: Enemy vision goes through object on spawned guard
Issue Description: I ran into an instance where the enemy vision algorithm seems to have been incorrect. I was in the "dragging a body" state behind a safe, and a drone spawned in due to the alarm level. The drone was able to see my agent behind the box. It's possible that breaking the safe with Dr. Xu also had some effect? Screenshot is attached.
Steps to Reproduce:
Stand behind an object, holding a body.
Guard/Drone spawns in due to alarm level.

Expected:
Agent is hidden

Actual:
Agent is seen.
