Odd Scheduler loop - by: dokeeffe

Apologies if this is a bug that has already been fixed. I havent updated in a couple of months (generally I dont update unliess I'm at the observatory to verify all ok)

So I was using the scheduler and normally its fine, works perfect. But I noticed tonight, it got caught in a loop. Easiest to explain by video below.

Any idea what could be going on?
