I treid to craft many ladders. It crafted once and then suddenly all receipes vanished. I cannot craft anything (except compressed stick). After that relogging does not fix the issue. Disabling the feature of automatic recipe unlock does not work. But removing Quark worked. The issue was triggered with many other mods but it remains when only Quark and AutoRegLib installed.

[Server thread/INFO] [net.minecraft.item.crafting.RecipeManager/]: Loaded 6 recipes
Tried to invoke /recipe give @A * and did not work
With mc 1.14 and quark r2.0-210

I didn't know that it has variant ladders

How did you fix this?

Was this just fixed by removing Quark?

I'm having a very similar issue. Cannot load ladder recipe. Can /give ladders to myself, and when I do, it says the recipe is unlocked but there is nothing in my recipe book. the ladder.jar recipe file is where it's supposed to be. I don't have the log files as I only know how to get them from my server and at the moment am dealing with some other issues, so I can't diagnose.

When I remove Quark I get the recipe back, but if I put Quark back in the recipe disappears again. I do not know how many other recipes this affects.

Does anyone know if this is a problem with the variant ladders just using the same namespace or something obvious like that? Something I can change I hope, haha...
