Auto-Scale Ghost Instances (AWS EC2)

Over the past week I have been testing Amazon’s AWS EC2 Auto-scaling with a few custom AMIs. Early today as I was cleaning up the auto-scaling configuration I encountered a bit of a conundrum – the auto-scaling API was returning a few instances that did not exist and was stopping me from removing an auto-scaling-group. After hitting Google I wasn’t any wiser, but it seemed that I did not dismantle my test setup properly, which was most likely causing the problem.
