I made a map yesterday on Avalanche, closing off the interior space of the central cave with the two man cannons. I cleared out all of the exterior spawn points in Slayer, Infection, King of the Hill and Oddball game types. When I began a Slayer match by myself, everything worked fine. But when I began a Slayer match with other players online, we all spawned outside of the cave! I went back to Forge and looked for spawn points outside but found none. We then played Infection and Crazy King with no problems, everyone spawned inside. Any ideas about what I did wrong? Thanks.
Did you get rid of the default spawn areas. You need to change the gametype in forge to see them and remove them. Also, I think that if you try and spawn opposing players too close to each other they will be spawned at new spawn points.
