[Bug/Error] Ranked games desyncing in 1v1?

[Ze_PilOt]

Retry in a custom game in sandbox, cheat on, try to spawn units until it desync, tell me what unit cause the desync.

yep, those two were games between me (Brainwashed) and Anaryl

first one was ranked, i left about a half min after the first dc, the game was rated and i lost
second was custom, we desynched again after about 5min game, and after another 5min game the desynchs stopped (for no obvious reason), we finished the game and it wasn't rated because of too many desynchs

[Myxir]

added two replays of us

the one on loki was before deleting faforever.faf from the gamedata folder
the one on palms was after

both always desynch after we build any airunit, t1/t2/t3/t4, even novax or drones, and it always stops desynching after the unit is dead/removed
