We utilize Amazon AWS instances heavily and take a lot of Snapshots. Recently I've discovered that if I add a create a new AWS instance based on a Snapshot of a machine that has a Tentacle already installed, when I add that Machine (via Hostname) to the Octopus Server, the Octopus Server will not warn me that there already exists a Machine with the Same Thumbprint.

This has caused a problem since Octopus seems to utilize the Thumbprint as an Identifier when deploying and I've accidentally deployed Code to the Wrong machine since the machine I was trying to Deploy to had the same Thumbprint as an already Existing Machine.
