I add an airbase to the global_layer.csv file in MAW and make the gsl file using the make_gsl.bat. I have done this many times in ETO and PTO with no issues. However in MAW the airbase does not appear and the aircraft takeoff that I have entered into a mission occurs at another nearby base. When I re-open the global_layer.csv file the base that I entered has been completely erased (or maybe the file has been replaced with the original version). Does anybody know what is happening and if there is a way to add to the existing global layer in MAW?
