Multiplayer with few friends we facing Desynchronization . after try to check all the mod . finally get is it this pyanodons HighTech having problem . i try 1.3.8 or old version also having that problem .do not know which item is cause it . but when disable this mod .everything is fine
Only thing I know how in pyhightech that could cause a desync is the blackhole generator. If you have any of them try deleting them and see if it goes away.
