Hey, I have recently joined a friends server. im not getting a bad ping (250ms) but im getting really bad block lag. this only happens with the new tekkit even when hosted by the same person. The interesting thing is that player movement is in realtime (no lag). just wondering if this might be a server bug or my type of connection. if you could suggest any fixes or explanitatons, would be appreciated. Cheers, Nz
