Not seeing anything hinting at Combat Nouveau in there.

I think this is the same as TerraformersMC/Biolith#26 which seems to indicate a timing issue of some sort between Combat Nouveau and Biolith. At the moment when The End first requests chunk generation, for some reason the server's biome registry apparently does not contain an entry for minecraft:the_end. That seems really wrong to me, considering the game has long since completed startup and I have never seen this issue until it was reported today. It does reproduce in testing with just Biolith, Combat Nouveau, and its dependencies.

After a very quick review of the mixins of Combat Nouveau and puzzleslib, it seems as though puzzleslib in particular may change the timing of various Fabric events to make them more similar to forge. @Fuzss I am wondering if you have any insight into this?

Puzzles Lib shouldn’t really change anything on Fabric‘s end. The only thing that’s done for my own events is rarely adding some conditions for mod loader parity in case you found that, but as said those are mine, nothing related to Fabric.

Maybe this is a class loading issue where Puzzles Lib touches upon some class too early.

Can the issue be reproduced with just Puzzles Lib?

Can the issue be reproduced with just Puzzles Lib?

No; I tested that and it did not reproduce. Combat Nouveau is also required.

Nope, it's fine - I use some of your other projects with it without issue
