• I tried the latest build (build refers to development builds not necessary a release version)
• I checked for existing tickets -
  If there are, please vote them with a thumps reaction and not create new ones

[TuxCoding]

From: #856

For the ProtocolLib error with FieldUtils, you'll need to use an older build of ProtocolLib. They are currently doing many breaking changes.

[kamil445]

I tried downgrading ProtocolLib to 4.8.0, now i can join the server, but auto login doesn't work

Is there a way to run fastlogin on 1.19 ?

[TuxCoding]

I pushed a new update. I didn't ProtocolLib truncated the older builds.

[TuxCoding]

The latest build fails, because I cannot target the newer ProtocolLib version, because it's not yet available for development...
