Ok, after about an hour of playing one of the miner is stuck requesting oak fence over and over. Must be thousands of request for this. The request gui for them took 3+mins to open. The clipboard took 3+mins also.

It cleared up by itself and the miner started working just fine. I don't think I did anything.

Yeah. The RS has healing mechanic that will track those kinds of things down. But the latest patch round by @Raycoms made this a lot worse.

Should be fixed in the newest version, should be on curse in a few minutes
