I've had the same issue too. Headless server desyncs when 2 players join. Tried on base 0.15.5 and 0.15.6. Removing the mod makes the problem go away, although you are left with a mod-gui button artifact.RaidSoft wrote:Hello!
I added shuttle train lite to an already existing .15 MP server, it started causing instant desyncs when the second player connected. Removed the mod and the problem went away.. Not sure exactly what the cause is unfortunately but the mod seems to have triggered it.

Not sure if there's a command that can remove it??
