I have been working on a semi-large scale redstone map, which uses a lot of command blocks and a few constantly updating redstone clocks (20,000+ command blocks and 10+ redstone clocks). Anyways, every now and then a weird glitch happens where all redstone/chatbox cease to function, but I am still able to move around and build. It has a similar effect as losing connection to a server, except it's a single-player world. This bug started happening a couple of weeks ago and has gotten progressively worse since (multiple times per hour of playing). I was wondering if anyone has had this kind of bug and/or if they know a potential fix? I have tried re-installing minecraft and turning down the graphic settings to near minimum. I have a Macbook laptop.
