Issue Title: Exploit & impossible overwatch
Issue Description: So since the recent update had the detention cell's guard back to the previous behavior(that the guard will stay on the investigated tile and will not go back to his original position), I exploited this as the screenshot follows, but recently several times the captain would find the prisoner who is at the back. As far as I know of guard behavior, this is not supposed to be happening, since investigating the site should only reveal the 180 degree line-of-sight. I did basically the same things in both cases, and I'm pretty sure this is a bug because there was one time something similar happened when I was doing another run, of which, unfortunately, I do not have any record.

The first three screenshots are a successful case of the exploit, and the last one is from the seemingly-buggy response of the captain, where the captain turns back and finds the prisoner.

Steps to Reproduce: 1. Have the agent and the prisoner at the back of the captain.
2. Get overwatched.
