Hello, I'm playing Enemy Within and Long War (Long War 3 Beta 14i-88-3-0b14i). After researching "Vehicular Plasma Weapons" (in my german version this is just called "Plasmakanone") I see the new available items in the research screen (Superheavy Plasma + Plasma Cannon (Aerospace)). However, if I want to buy an item (by clicking on engineering->build/buy items) the menu doesn't open and the game crashes. I have the same problem with the research "Pulse Lasers". Both research items unlock weapons for SHIV/Aerospace that aren't in the original game. Mabye this is the problem. I have uploaded my save game, with plasma weapons research nearly finished. http://workupload.com/file/cUlj4Gt9 I play long war in english together with my german enemy within. I have a mix of both languages in my game interface, but until now everything worked fine. Maybe someone can help me, so i can continue playing this great mod.
