O.K. I just think everything is working when I get back to square one... Apparently the game is unable to find infrastructure from the stock 'INF.bgl' or Pen's replacements... Nothing of the stock infrastructure shows up in the Mission Builder list but everyone else's does, whether it is listed in 'mdlnames or not.. When I try to load a landbased mission, I get 'cannot finds for damn near everything in the stock INF library.. I'm beginning to wonder if it is a PC glitch but I don't have a problem in a new install until I start re-adding the add-ons. Help!!!..
