errors and crash after starting network game

[andy5995]

At commit 6f3a6fa, we got some errors at the top after starting a network game with 2 players.

ERROR: PlayerID 3 |   bad path from 2 to 57 ??? (void 0)
ERROR: PlayerID 3 |    regionLinks start []
ERROR: PlayerID 3 |    regionLinks end   []
ERROR: PlayerID 4 |   bad path from 2 to 57 ??? (void 0)
ERROR: PlayerID 4 |    regionLinks start []
ERROR: PlayerID 4 |    regionLinks end   []

And then a crash

ERROR: Cannot serialize NaN values.
terminate called after throwing an instance of 'PSERROR_Serialize_InvalidScriptValue'
  what():  Serialize_InvalidScriptValue
Aborted (core dumped)

This probably doesn't add anything useful, but it also happens in single player games. Here's when I start a game using the Acropolis Bay skirmish map

ERROR: PlayerID 2 |   bad path from 2 to 17 ??? (void 0)
ERROR: PlayerID 2 |    regionLinks start [20, 21, 9]
ERROR: PlayerID 2 |    regionLinks end   []
ERROR: PlayerID 2 |   bad path from 2 to 18 ??? (void 0)
ERROR: PlayerID 2 |    regionLinks start [20, 21, 9]
ERROR: PlayerID 2 |    regionLinks end   []

yes, this error with regionlinks is no harm as far as i know, i ll hide it.
serialisation is major issue

yes, I noticed this too. Apparently it's harmless for singleplay games, but it does cause crash in multiplayer. It happens on most but not all maps.
