mhm got the problem too since two days. When my budy visit my home i can't open my doors or boxes anymore. My budy can see the door open and closing. He can walk trough and me not. Yes, the door that i opened and could not see a move on my site . When he left my home everything works well again. so it must be some syncerror cause its only when we where close to each other. We played two weeks whitout any problem. The home grows bigger and the time to load the objects at gamestart raised also really hard. It will took more then 15 sek to load the nearest objects now. Internetconnection should be allright with 100Mbps down 40 Mbps upload. Ping of the 3 players arround 26 ms and my ping arround 1 ms because its the same network. Taskmanager shows upload arround 1Mbit/s download arround 1.6 MBit/s. Iinstalled the dedicated server on my maschine. I've got a Dell Precision Server whit two xeon 2x6 core 5% usage . 84GB Ram > 5Gb usage. . Tried to update server, restarts, Steam-filecheck :/ The Problem is since i updated the server two days ago. At this Time our fourth player begann to play this game whit us too. Everthing worked smoothly and well for weeks and now its not able to play togheter anymore. And now we found out that there is no problem when we travel to a far outpost togheter with less biulding objects. Last winter we've been arround 6 players whitout this problem. !Objectsyncproblem! Actually we testet with only 2 players ingame, the same two players that played smoothly for weeks togheter. May be its the hardware? Routertroughput or packetsync? please send us help ;)
