Spring RTS Engine

Trying to play Spring with various mods including Balanced TA, and NOTA v1.40 and he desyncs constantly. At first i thought it may be his connection but it's persistent and at least for the first little bit he always desyncs on fram 16 and 417. Anyone had this problem?

A desync only happens once, any later messages are just to inform that it has desynced (checks only every so often). Most likely frame 16 is the first it checks on so the game is desynced right from the start. I know mod options can cause something like that to happen if one player uses SpringLobby but I think that's been fixed already.

Yeah, i've tried just about everything i can think of game wise. Had him reset connections, check drivers, check network settings we tried different sized maps...i don't know what it is.
