I am trying to play with a friend, but we had trouble with "Uploading Map":

Normally the map upload speed rounds 15-20kB/s (most of the time 18.2-19.8kB/s), this is by default an issue when the map is >8MB... { 8MB*1024KB/MB = 8192KB / ~20KB/s ~= 410s ~= 7min }

Furthermore, sometimes the speed starts to increase up to 40KB-50KB/s but then the connecting player "stops responding" and the server (me) disconnects him automatically... forcing to re-download the whole map from 0...

Is there any fix to this?

Thanks in advance!

You could try removing the replay.dat from the save. That should reduce the file size at least.

Thanks man ! It reduced the map weight / 2, it was nice (as a fast-fix), but would be nice if the developers find some kind of permanent fix.

Greetings !

I am also having this issue. The map transfers at around 600 kb/s but at around 8 mb the download fails.

Removing replay.dat worked for us too.

This solution presumably won't work in the long run. Any thoughts on a proper fix?
