I just played some multiplayer with a friend using this mod, robot army, and nothing else. It worked great. Given that long list of mods... Probably something else was going on.

Can confirm, with the mods on this list one is unable to join a multiplayer game in progress because of desync. Removing only this mod resolves the issue.

If I can provide any more information please ask; this seems like a great solution to high complexity builds early in modded games, before access to construction bots.

Pretty sure the problem was a conflict with my mod and bottleneck. Should be fixed on my side.
