Bug or feature? One way door
I found this potential bug or interesting feature in another one of my bases on accident, then replicated it in this new base for a fun gimmick. Using a certain setup, you can make a one way hole which allows the raider to pass through one way, but not another. The base layout was designed so the front door or back door can still be viable.
I'm leaning more towards this being a bug since I could easily abuse this if I wanted (ie: tomb trap you can't escape from). It is a fun feature if used responsible though. If any devs comment that it's a bug I'll remove it from my base and delete the post so as to not spread the knowledge until it can be patched.
