hey guys, i've been playing this mod since it first came out on Emergency 3. On top of that, i've been playing the entire series. Today i reinstalled EM4, just to relive the fun i've had. I've downloaded the mod and this mappack. However, suddenly i've got 2 LA mods in my modification menu inside EM4. one says 2.1 the other one says 2.0. The 2.1 is the original mod with the map the dearest Mister Hoppah included. The one that says 2.0 has, i guess, the new map 'cause i've never seen that map before. But when i start that one, i have very few traffic, only the regular EM4 units and all the stations etc say: unknown prototype building. Can anyone help me with this? What have i done wrong? Thanks in advance. Kind Regards, DragonSlayer666
