I'm preparing the next version of the BIG Reference Card and because of layout and content issues it's now extended to a few pages. However I have a little bit of room to fill so I thought I'd try and include some rules snippets that cover common mistakes. So far I've added the rules for Auxiliary Firing Arcs, Deploying Docked Ships from other ships and Large Ship Barrel Roll.
Is there anything that you see commonly/frequently coming up? Newbie mistakes? Common misconceptions?
Any input is greatly appreciated.
Cheers
