So, I made a melee map. It consists out of 4 spawns no goals and random blocks. The map type was set to "MeleeArena" and the flag in the bottom-right cornor is green. I calculated the shadows and started the LAN mode. Gamemode "Script" whatelse should it be I can only change it to "Script".

The map loaded, I spawned and I'm shooting around can do everything. Then my friend joined. And he is not spawning. His name is just darkened in the scoreboard. He IS in the match, he can chat, I can see his avatar, his colourful name. But he dosen't spawn at all. I restarted the map too, with no change at all. (He's not in spectator mode also.)
I'm really clueless. And I would love to play some 1v1 matches with my friend, but yeah.
Thanks in advance for any help.
