Title: Pistons stuck on Version: 1_0_3 OS: Windows vista ultimate x64 service pack 2 Java Version: Version 7 update 40 Description of Problem: I'm having this problem where pistons get stuck on with no power even if there's no blocks around them they just float there and there still on.My redstone creations work at first then after awhile some of the pistons will glitch and the only way to fix it is to build it somewhere else.I remember having similar problems when i used to play vanilla mc last year so i'm not sure if its a glitch with minecraft or tekkit but its made the game unplayable for me.I tried updating java and removing optifine the only mod i'm using with tekkit but nothing works i have minecraft version 1.5.2 does anyone know how to fix this?
