@AeroScripts Any news on this?

I usually see it once when I'm in a raid group, and only in raid groups.
Don't think it's in 100% of the raids though and I can't really find any pattern in when it happens.

Saw it again today in a raid. Was just standing still at the start of MC and we were buffing and the error popped again.
It could also be due to offline people (in the raid) logging on while we were standing there.

This has been fixed and will be released very shortly with v6.0.0

Were you in a regular party, or a raid when this happened?

No, soloing

You're totally sure you weren't in a group when that happened? Are you in a guild

The reason I ask is the error is related to quest progress sharing, which should only happen if you are in a party

99% sure I've not been grouped when I see this.
I am in a guild though.
I'll take note of it next time it happens.

Only seen it at times when I'm in a guild raid. Not often, but once in a while
