What CAN affect flags is haveing any tga's bearing the same name as existing
flag name tga's.
Also ID conflicts could raise the same issue.
As We all keep throwing more and more at the SH3 Engine?
It's getting picker and picker.
In GWX 2.0 Aircraft we saw pilots and crew vanishing!!
We found that renameing ALL tga's AND the final name assigned solved this.
So your tga may be called whosit.tga but the final name is Default!
Change both!
I rename everything now.
May not be your problem but it's good info!!
