Tried with a new instance in multimc and I couldn't get mob drops or loot table to work. I'm a little confused about what was said about world profiling. Does that feature exist in this version or no? I'm guessing no from this

found it. updated the title. jei advancements makes the mob drops & loot tables disappear.

I'm gonna do a few more tests, it seems to be working again without changing anything afaik. I'll report back in a few mins.

I also found an incompatibility with Ars Nouveau 1.23.11 and JER 0.12.1.128. On the 12th page of mob loot, it crashes.

Fixed the title to be more clear. The crash log can be found on ars-nouveau github page.
