Hi, i'm using latest spigot dev 1.17 and latest protocollib dev and latest fastlogin dev and latest authme reloaded dev and i'm getting this error, fastlogin's developer said me it was fixed and it was related to protocollib, but i still have this error.

Duplicate of #1221 - Only FastLogin related.

I said that you need to update the ProtocolLib version to support the new class name changes. What I didn't know is that you have that, which I can see here (~[ProtocolLib.jar:4.7.0-SNAPSHOT-b510]). However I missed that our CI didn't built the new version. So I now released a new FastLogin version on the GitHub page.
