Describe the bug
Cannot retrieve entity from ID when upgrade ProtocolLib from 4.6.0 to 4.8.0.

Server version: 1.12.2 Paper

I also tried to upgrade the error reporting plugin to the latest version, which didn't help anything.

I was having this error as well.

I tried 4.7.0, and it's the same problem. 4.6.0 and 4.4.0 is work fine.

@dmulloy2 me too

This is caused by all listeners being in async by default.

Newest version of protocol lib adds a listener option for forced-sync listeners.
