Title: Tekkit Server Problems Version: 3.1.1 OS: Windows 7 Professional Java Version: Java 7, Update 5 (build 1.7.0_05-b06) Description of Problem: Sorry for not making the title more descriptive, but I can't explain my entire problem so easily. So, until recently, my tekkit was working fine on servers. But just a couple days ago, a weird problem started occurring. When I stand on the pressure plates to open my Iron door, it does not open to me, but for everyone else it is. They can walk through it, but I can't. When I flick a lever to try to turn on my machines, it takes quite a bit before it actually changes sides; and even after that the machine looks really laggy. I see stuff that popped into another chest a minute ago go through the pipes. Whenever I place blocks, they don't appear for a bit unless I reconnect. Also I constantly get "End of stream" errors and Java.IO.IOexception(Not enough data), but chat doesn't lag. People say I am just having lag, but before it was working perfectly. I have tried redownloading my tekkit installation, reinstalling Java, but it doesn't help. Error Messages: End of stream Java.IO.IOexception (Not enough data) Error Log: N/A
