Crew members keep pacing back and forth?

I was doing some decorating on my ship, and I blocked off one of the doorways connecting two floors. Ever since then, one or more of my crew members have been pacing back and forth over one specific spot where I blocked off the doorway. Just now almost my entire crew were doing it, there were six people pacing over the one spot, and they've been doing that for five minutes. How do I get them to stop?

 

The only way I know to fix that is to break the area they are pacing on then replace it.

 

I did that, but they just start again after a few minutes

 

I have taken to locking them in the cellar part of my ship. They haven't bothered me since.

 

Cruel but effective,now if your a true arse youd propably fill the room with some horrifying liquid.Maybe even multiple liquids.

 

Healing water, as they feel the horrible pain of drowning they just can't die because it makes them live.

 

Oh god

 

From a simple discussion into a really creepy discussion.
