I think removing “empty stacks” doesn’t work very well. I have 2 “empty stacks” which actually are doing a “VPN lookup”, mostly because I don’t want to create the VPC at the moment. Those are deployed fine now, but I tried removing them and it failed.

Stack amouly-xxx-vpc-stack
  Status: failed
  Error: The amouly-xxx-vpc-stack stack failed to destroy.

But removing from CF console works fine.

Hm strange I'll make an issue

Ok, cool.
