I was always playing in "1.7.10" while I was waiting for creation for blocks and items. When I noticed "22w13oneblockatatime", I thought about playing it for fun and making it my fun world some time. However, in this version, there was a lot of lag. Some lag was like 1.5 minutes. One of the lag moments, it was like 3.5 minutes long and crashed the game with exit code: 6. This lag issue was weird. This lag issue happened 3 times in a row. This lag issue did not happen in "1.7.10". I guess this lag issue is from something going on in this version.
