For the last patch we split the error code in two. It used to be two separate issues that could produce that same code, the new error code is Longbeard. We've not introduced a new error here, we've just renamed an existing one.
We also fixed a potential issue that some people might have hit that caused Cyanbeard or Pastiebeard previously.
From what I can tell, the number of Cyanbeard+Longbeards has dropped a bit, and the number of Pastiebeard errors has dropped significantly.
We're actively looking into additional causes of Longbeard currently but following the steps for Cyanbeard might help some people.
