not because of my plugins. I tested it on a clean server too.

Looks like we send an inventory packet that the server doesn't like. I'll look into this more tomorrow.

Looks like the issue here is a little deceptive. Making a custom villager with that buys emeralds for an enchanted book works fine, which one can verify by trading with this villager:

/summon villager ~ ~-2 ~ {NoAI:0b,Willing:1b,LastRestock:0,Xp:0,VillagerData:{level:1,profession:"minecraft:librarian",type:"minecraft:desert"},Offers:{Recipes:[{rewardExp:1b,maxUses:2147483647,uses:0,xp:1,priceMultiplier:1f,specialPrice:1,demand:1,buy:{id:'minecraft:emerald',Count:10b},sell:{id:'minecraft:enchanted_book',Count:1b,tag:{StoredEnchantments:[{id:'minecraft:loyalty',lvl:1s}]}}}]},Brain:{memories:{"minecraft:meeting_point":{value:{pos:[I;0,0,0],dimension:"minecraft:overworld"}},"minecraft:home":{value:{pos:[I;0,0,0],dimension:"minecraft:overworld"}},"minecraft:job_site":{value:{pos:[I;0,0,0],dimension:"minecraft:overworld"}}}}}

Rather, it's the book being an input causing the issue.

Yea, I can use commands. but how about players? I'm hosting a survival server. And they will make their own villagers ???

I'm noting down what I'm finding about this issue. Ideally I'll find the root cause of this issue instead.

Oh nice. I hope this will fix in soon ._. Good luck
