I dismissed 5 crew members and I got no bunks back in return.

Gnomon: Without seeing what happened on your account or more info, it's hard to tell what's going on with the Bunks. Panman69 may be right about an overflow issue.   I'd recommend reaching out to our Support team. They have access to your information and can see what is going on with your Crew/Bunks: Contact WG Support   From the drop-downs, you can select: In-Game Goods --> In-Game Goods Lost and Found --> Crew   Then, just provide details on what occurred and what information you're requesting. They'll get you sorted.    Hope this helps!
