There is nothing wrong with ArgoFlag LV, since I actually had to download my own ZIP file and use that to mod my game (I forgot my own at first :roll:).
If you didn't find vegasflag.txd, then you might of typed the search wrong.
Otherwise, the flags would just be white (if there was no file).
Try and find them again, remove all the vegasflag.txd files, then add the new one again.
So yea, nothing wrong with those.
Tried and tested.
