For this to work some extra beta slots have been created, 8 for Sx tracks and like C:\program files\Steam\steamapps\common\ mx vs atv reflex \ MX vs ATV Reflex launching the beta slots crashed. This track exists outside the "Beta Slot" system, making it a permanent I've never expect something like this and that the tracks are not in beta slots. . In my tracks my mx vs atv reflex crashes if i put in some sort of trees. I forgot to mention that you need the beta slots to use these custom tracks, use the links below to download all.
