Yea, as DC and the game itself says, there are still some obvious bugs.
One partial-solution I've found is running a custom map server using the dedicated server tool generally allows multiple people to download the map, and not just one person. Without the dedicated the first person to join is the only one who can successfully make a connection.
And you can join your own dedicated server, as long as you set the server port to something other than 36963 (I usually use 36966). But I think in max you can also change your client udp port as well, so just as long as your client and server udp's are different.
EDIT:
Ignore what I guessed up there. I've done some more testing, and it appears maptransfer will only give a file to a single client if there is only one file to give (i.e. if the only resource required for the map is the *.map file). My hypothesis is the map transfer doesn't like sending the same file repeatedly to different clients at the same time. When there is more than one resource to send (like a *.map and *.txt), it alternates between them, thus it is never trying to send the same file twice. edited 1×, last 31.07.08 11:23:56 pm
