Title: Cant harvest any blocks on my server Version: 3.1.2 OS: Windows 7 Professional(64bit) Service Pack 1 Java Version: Java RE 7 64bit Description of Problem: I created a tekkit server recently, but when I logged in I was unable to harvest any kind of block. The blocks pixilate as they start to break as normal, but when they should break, they instead just respawn just as they were, and I don't receive any resources. Any help is much appreciated!!!
