1.12.2 profile command freezes world server
tyon2006 opened this issue ยท 6 comments
Hello! I am running /jer_profile 1 0 in single player mode and it seems to freeze the world server. The client continues to run, but blocks stop ticking and mobs stop moving when I run this. I've run this as long as 10 minutes before closing down. Can you provide guidance on how to run a profile for the overworld or help address as undesired behavior?
Looks like the random sampling of chunks causes some issue with the generation algorithm, which might only behave well under ordinary chunk generation. While I've been maintaining CustomOreGen since like 1.4.7 times, I'm not the original author, and don't fully understand all of the algorithms. A possible fix would be to pregen a sufficiently large part of the world and then sample it.
Freezing should normally not happen, but is possible especially when doing large scans.
Is there any spam in the client log when you do something link /jer_profile 10 all ?
I tried that exact command and this is what I got:
Looks like a incompat with customoregen

Looks like a cross mod issue with CustomOreGen, would also report to them. I don't really support 1.12 anymore, but if needed I can make a fix if we can figure it out.
