Looks like someone else is having somewhat a similar problem as I have. This happened in single player, using the mission editor. At first I thought it was the "holy tac texture" problem with the MiG-21Bis but no holes (because I entered the correct numbers of digits according to skin used). However, if I were to change to a different MiG-21 skin (downloaded custom skins) that has no bort numbers, the old skin shows through (sometimes something that looks like enlarged numbers) where the old bort numbers were supposed to be. I tried shutting down DCS and restart in ME to see if it resets, the same problem persists.
So I experimented by changing to a MiG texture that has no bort numbers in ME, saved and got out of the game, shutdown my computer and started back up. The texture displayed correctly in ME. No strange stuff, no holes. I then switched to a custom texture with no bort numbers, the new texture still displayed correctly and no funny stuff. I proceeded to switched to a texture with bort numbers (i.e. a Russian version MiG-21) the bort number shows in the correct position, no funny stuff either. But when I switched back to the custom skin without bort numbers, the problem with the old skin/funny characters showed through where the bort numbers were, came back.
