Known issues

This PacketEvents update was a rather large one. We acknowledge that it still has a few issues and plan on fixing them in the upcoming patch update.

1. MappedEntity#isRegistered call leads to NullPointerException

Network synched registries are currently being worked on. https://github.com/retrooper/packetevents/pull/866 Completion of this task should lead to the issue being resolved.

2. EntityMetadata issues on 1.20.5+

Some metadata types (eg. spawned wolves) cause issues due to them being implemented incorrectly. Also this, we plan on fixing in the next patch update.
