Boarding on the Defiant after the Beast of Winter the Steward informs me about a misterious crate on the Defiant but I find no crate to start Seeker, Slayer, Survivor.

Am I looking in the worng places? Where the crate should be found? Should I restart a brand new adventure?

Thank you

I found mine on a lower deck behind one of my crew on a right side of the big storage space (as if under the stairs you decent into). In another thread one of he devs mentioned that there are some issues if you are using the submarine, and switching to another ship resolves the issue for now.
