First bug report so let me know if more info is needed. I was in the fleet composition screen and had just put together a custom fleet (as opposed to hitting "AUTO-FILL") consisting of standard designs and received the following error when I hit the "MUSTER" button.
[GAME VER] 0.8.19_UPDATE_8.1 - KIRK

[CPU] 3 x AMD Phenom(tm) II X4 955 Processor
[OS] Windows 7 Service Pack 1 (6.1.7601) 64bit
[GPU] AMD Radeon HD 5700 Series
NullReferenceException: Object reference not set to an instance of an object
Since this is my first bug report here are some more system specs:

Let me know if there's any more info that will help.
