Bug description

You can cycle trades once on a summoned villager with custom trades.

The cycling option shouldn't be possible on villagers with custom trades, you can't prevent players on a server to mess up your custom villagers.

Minecraft version

1.20.1

Mod version

1.0.7

Mod loader and version

Fabric Loader 0.15.10

Steps to reproduce

1. Summon a villager with custom trades : /summon villager ~ ~1 ~ {VillagerData:{profession:fisherman,level:5,type:plains},Invulnerable:1,PersistenceRequired:1,CustomName:""Didier"",Offers:{Recipes:[
   {buy:{id:cooked_cod,Count:10},sell:{id:emerald,Count:1}},
   {buy:{id:cooked_salmon,Count:10},sell:{id:emerald,Count:2}}]}}

2. Open the villager trades GUI

3. You can cycle the trades once

Expected behavior

Not being able to cycle trades from a villager with custom trades

Screenshots

This won't be a thing. This is only meant for villagers with professions.

But you can't summon villagers with custom trades without profession.

Removing the profession tag or setting it on profession:"minecraft:none" won't allow players to open the trades GUI as the villager is unemployed.

So you can't have a server with Trade Cycling + villagers with custom trades ?

If the trades are manually being added with a command, no. Modded villager professions or trades added to the professions will work fine.
