NBT isn't changed and entities despawn

[berwil-1]

When using the latest version of PowerNBT on a Paper 1.16.4 server NBT isn't changed and no errors are thrown.
Furthermore, when entities are selected with /nbt id(0) they despawn instantly (also without exceptions).

Thanks for the report. The plugin is not supported for 1.16.4 and the nbt has changed a lot from 1.11 to 1.16 so trying to replicate the functions from 1.11 is difficult and won’t be completely implemented for a while.

The rewrite of NMS should fix this however I'll leave this open until I can confirm.
