I took a mission to find someone in a close by system, jumped there and got attacked by the {wanted}. I installed 10 s2 guided missiles. I launched 3 and blew up {wanted}. Jumped back to Sol and this crash happened. I think the issue is on master and not on the findperson PR, placing it here for the time being.

I'll look into this one - the stack context indicates a station market is not getting properly initialized or deserialized before being updated.
