Crashlog Check

• I understand if this is a crashbug and I did not attach a crashlog, this will not be handled

Fabric Check

• I understand if I am using Farbic APIs or Connector, this will not be handled

Nvm, I figured it out. Server was apparently outdated, but was letting me connect to it the other night with different-version clients.
