When everyone logs out of my server all the redstone freezes. The clocks all stop and nothing updates. I have to go round and reset all the redstone by replacing some torches every time I turn my server on. I'm confident this isn't the fault of a plugin as all I have installed is DefaultCommands, WorldEdit and otherblocks (Not configured). This is really annoying because we have some redstone in awkward to get to places. Sorry if this is a known bug, but does anyone have a fix? Is it just me with this problem? I'm running build 684 but it happened on the previous build too. Oh, and I am on Windows 7 x64.
