Console/log filled with repeats of

[08:22:00] [Craft Scheduler Thread - 50/INFO]: Queue = 1

Are you sure this is from mobhunting? It does not look like the debug information I make?

Not sure, since it's not identified. :(

I updated three plugins, trying to isolate. I'll run isolation again.

I might be me, because I have improved the message queue for the action bar messages...

I think it's someone else. Apologies.
