I downloaded a CoD WaW zombie map and so did my friends I guess it's using the standalone. When I invite my friends they join and then get kicked out immediately. The only maps that work are minecraft because its not using UGX Standalone, Can't I just play with my friends? I have Bikini Bottom and FNAF and they both kick out my friends and when I start the game when they join it says "Co-op Campaign - Semper Fi" There is no option to change it from "Campaign" to "Nazi Zombies" So the UGX standalone took out that option to fuck with us? Please help this is irritating.
