this makes little sense.
AssignPlayerToTeam is a synced callout, so upon reconnecting the client will simply execute it again. you are either claiming that it doesn't get called a second time or that the second invocation has no effect, paths which should both lead to a rapid desync. provide more evidence as well as a *minimal* testcase.
>you are either claiming that it doesn't get called a second time or that the second invocation has no effect
I'm claiming neither. Let's assume Assign happened at time T and the reconnection started at time T+X.
The reconnecting client reaches T. He correctly invokes Assign again and it correctly changes his team. There is no desync.
Then he (and other clients) reaches frame N+X upon which something happens that reverts the team. This happening seems to be synced as well since there was no desync in the replay. I believe it's this line https://github.com/spring/spring/blob/30862626214bd263b1c4489bb197ef1c3dbc0738/rts/Net/GameServer.cpp#L2886
Here's a replay (non-minimal but fairly short) in which player 3 [hokomoko] is affected: https://zero-k.info/replays/20180623_174023_La%20Isla%20Bonita%20v1_104.0.1-287-gf7b0fcc%20maintenance.sdfz Zero-K v184.108.40.206 (engine is old-ish maintenance but I believe the relevant parts were not touched since)
I'll try to prepare a minimal replay if that's not enough.
it may be sufficient to move the SendData loop after the SendJoinTeam.
I am however not going to touch this or any other issue so long as ZK remains on 287.
