How to force root stack update when nested stack is in state DELETE_COMPLETE?

Question

I had to delete nested stack, but I cannot update the root one now.

I get the following error:

Stack is in DELETE_COMPLETE state and can not be updated.

What should I do to make CFN update root stack and recreate the nested one?

Your only options:

Delete the parent stack and redeploy.
Remove the nested stack from the parent stack's template, deploy. Put the nested stack back, deploy. This will trigger a CREATE event for the nested stack instead of an UPDATE event.
