Prussia - Crash to desktop

[iNemanja23]

Description
On the 23rd February 1865 at 2:00 the game crashes to desktop. That is two days after an order of ships is completed, which also completes the highsea fleet mission (35 ships total or 20 capital ships). The game crashes no matter if the event for the ships arriving is completed (by completing it I mean clicking on the popup which gives you the ships) or not (which also means it is not tied to completing the highsea mission.
