Not all CNAME records created when instances are launched from auto-scaling group within CloudFormation template #1

I wanted to thank you so much for publishing the whitepaper on dynamic DNS for Route 53 using Lambda and DynamoDB.

It works great!

I did come across one little issue, it just doesn't create CNAME records for when instances are launched from an auto-scaling group within a CloudFormation template. It does create CNAME records for when I launch the instance(s) manually.

UPDATE: I made sure to clear the DynamoDB table before launching the same CloudFormation template and for some strange reason it created 2 CNAME records but it didn't create all the CNAME records for the other instances that were launched. Maybe Lambda is not able to catch all of the instances launching at the same time. I am using the same tag you mentioned in the documentation.
