I was on the TF#3 server last night in a Martlet flying with a US skin and it was showing the wrong tail number, instead of YOY22 as I ususally use it was XNX I think and I can't rememebr now what numbers. It seemed that the letters get out of sync by one at some point. Putting AAA in correctly showed A's if I recall correctly.

When I tried to correct this by putting in the relvant letter to show as a Y (Z I think it must have been) the Y seemed to be there but was too large and was clipped.
