Relevance

• I tried the latest build
  (build refers to development builds not necessary a release version; i.e. v1.10 is out of date)

• I checked for existing tickets -
  If there are, please vote them with a thumbs reaction and not create new ones

[rursache]

maybe similar to #878 ?

[games647]

Which ProtocolLib version do you use?

[rursache]

Which ProtocolLib version do you use?

@games647 as stated, ProtocolLib version 5.3.0-SNAPSHOT-721

[games647]

Yeah looks like they removed the class in the newest commit. Please downgrade to a version
of ProtocolLib before dmulloy2/ProtocolLib@47bcd53. So for example dev build 720. I cannot fix it atm, because I'm only available on mobile.

[rursache]

thanks, using the 719 build fixed it!
should i leave this issue open? seems like a fix is required on FastLogin side to support newer ProtocolLib versions

[AmZuppa]

does 720 work? @rursache i found out that 719 build got a big error that makes the server crash. they say it's fixed in build 720

update: ProtocolLib build 720 does work, and it should fix the crashes.
