SERVER jar. You are on 1.21-DEV

SERVER jar. You are on 1.21-DEV

Same error on 1.21.1

SERVER jar. You are on 1.21-DEV

Using papaer 1.21.1

This problem occurs when disenchanting in vanilla mode, items that have custom enchantments and these items are older than the current version that the server is using, that is, before 1.20

Put an item with custom enchantments in a chest in version 1.20.4 or 1.20.6 and then update the server to a version higher than 1.21 and this problem occurs

Reviewing this error, I noticed that it said GrindstoneEvent, I searched the kit room for all of them and started testing them one by one until I realized that the oldest ones (created during 1.20.4) were the ones that were giving errors.

We'll try it out. Probably an issue with converting nbt to the new components system on 1.20.5

Yes, it only happens with items that have been created before 1.20.5 and the server is currently on 1.21.1

Could this bug be prioritized? Since we have many objects with enchantments from before 1.20.5 and the console gets very saturated like this
