Im having the same error, IM using latest MMOitems and MM build on Paper 1.14.4 (bc I still got other plugins who need to be updated) the item drop is a core feature for my server, which I really need to make it work, I'd really like if they could priotize the item drops.

Same issue here.

Latest 1.16.2 paper, latest MM dev build.

In the provided logs, it's saying you're using a version of MM that isn't compatible with 1.16.2?

[11:57:48] [Server thread/WARN]: [MythicMobs] This version of MythicMobs is not fully compatible with your version of Bukkit.
[11:57:48] [Server thread/WARN]: [MythicMobs] Some features may be limited or disabled until you use a compatible version.```

Yes, but I'am using latest devbuild (3432 and then 3434 since this morning and there is still the same issue)

This should be resolved in build 3435

Not fixed

still having issues

I reopened this issue which is still happening.

Tried latest dev build, so I can approve, even default drop is not working (via /mm i get )

Apologies, something seems to be broken with the build bot and it did not push the appropriate changes to the website. My local builds definitely have this fixed. Should have a resolution shortly.

This issue should be fixed in the latest build. Please try it and reopen the issue if you encounter more problems!

fixed

@ashijin Something still wrong, items can't be stacked with items dropped from prev. version Nothing changed in config https://youtu.be/-Vrph8iJ7Nc <--- demo what happend

https://pastebin.ubuntu.com/p/mRmck5nRdG/ <--- item configuration

Also new items cant be used as trade currency anymore (via Shopkeepers plugin) Item name, lore and NBT tags count is similar.

[Legacy attachment omitted]

Using powerNBT plugin I've found the diff in display.Name NBT tag 2 similar items, first generated in MM 4.9.1 and second one in from 4.10 dev build

I think now I should replace all my items.

The change in NBT values is an unfortunate side-effect of the new 1.16 text formatting to support all the new colors

I am still having this issue too.

• MM Build #: 3456
• PaperMC Version:1.16.4 #275

I create the following item in Items/items.yml:

RedLeatherChestplate:
  Id: 298
  Data: 0
  Options:
    Color: 255,0,0

And then here's the error I'm getting:

This occurs for any and all items.

I found the issue was because the latest free version of MM is not compatible with 1.16.4. I purchased the premium version and used the latest dev version which solved the problem.

It may be useful to users to communicate which MM versions are compatible with which MC versions.
