Game and Details! version
C201
v1.13.3

In the most recently version of Details for classic. (https://www.curseforge.com/wow/addons/details/files/2945466)

There is both LibThreatClassic2 AND ThreatClassic-1.0 in the Libs folder.

Is this intentional? Could this be causing conflicts?

Those libs has been removed.

Threat has seemed to be inaccurate for weeks now. I'm also curious if this is the issue.
