Greetings, Player. I am here to report an issue with chunkloading.
You see, I use an extended IDs mod called 'NotEnoughIDs'. More info and the source code is here: https://goo.gl/o4o616.
Anyways, 1.21 crashes the mod entirely, and 1.22 test builds cause near-impossibly horrendous chunkloading. (one or two 16x16x16 areas at a time)
Is it possible for you to fix this bug?
