Then what explains the missing assets ? I removed the mod and the tanks returned, should I take some screen shots ? Like, some assets remained, though they changed in appearance, colour etc, they not longer looked the same as the originals but were named the same, which made me think some were replaced, I honestly can't find any other reason why, as once I removed the mod, the original tanks returned.

I don't believe so, as mentioned, after I removed the "BlueDog" Mod. all the original tanks came back and when I install Bluedog they get replaced with others, though some still remain original

The MOD add's parts ? huh ? it seemed to over write parts at my end, my fuel tanks were left in a god awful mess, with tanks missing completely, it didn't go back to normal till I removed the Mod, is the MOD meant to over write existing assets ? or add new assets ?
