Went to Github. Didn't see where to put this.
But then again, not sure if this is the right place to report either.
2020.10. First time using it on this machine. (Updated earlier today.) When opening this sequence/directory, I received a message that a group could not be processed. Went in to look at the groups to see why.
While accessing the group models xLights froze and then a notice of a crash report being saved came up. That crash report is attached.
Group shown as a problem was "MH" (no quotes).
Image of the error message also attached.
