Spring RTS Engine

If someone hosts a replay in the lobby, then when other players join to watch, they see the replay-players with incorrect colours. This seems to sometimes translate into problems when starting the game - players in-game are incorrect colours and stick on game start - could this be because the client thinks they have the wrong player number...

This probably happens when trying to host pre-0.73 replays, can you confirm this?

You shouldn't be able to host replays from a different version at all, since the exe is different and therefore the sync wouldn't work, right?
