Logged in tonight and found an odd little graphics bug. Both the gun sight and the armored glass in the P-38G looked too dark, at first I thought maybe my gamma was off, but when I started the engines and moved my view both vanished. Shutting off the engines brought it back, but as soon as I started them again everything vanished. I took off and went looking for a fight, as soon as I dropped my DT's when I was engaged by a P-51 things returned to normal.
I did save the film if it would help.
*edit*
After I dropped tanks and things looked like they were back to normal firing the guns would cause the glass to disappear while the guns were firing when I let go of the trigger things returned to normal.
