I can pretty consistently replicate this issue. Useing the redstone link from the create mod tends to "freeze" the server. No tick updates, block braking doesn't register. After a while I boots me from the server saying that the connection was lost and that it "Timed out."
The server stays on but I can't join in, saying the same errors. It says that im still in the server when I'm not.
It does fix itself eventually after a few minutes but because of how consistent this issue is I wanted to know if there were any fixes I can attempt to at least mitigate the problem.
