"Reprovision" deletes the machine and does not reprovision?

What's up with this?

This afternoon I was testing the following process:

• Deploy Linux machine successfully, got machine deployed successfully.
• Changed the blueprint under Infrastructure –
  Machines – Managed Machines to Windows DEV/Test
• Changed the associated reservation for compute
  and storage
  • At this point, the machine appears to be a Windows machine, although it is still
    running Linux.
• Ran the ‘reprovision’ operation, which succeeded
  immediately… after having deleted the machine.

Obviously this is bad. Has anybody else seen the "reprovision" functionality delete their VM? I'm thinking of using this for cases where an application has been deployed with one OS, that needs to be tested on another keeping all of the security rules in tact (eg. firewalls for specific IPs that were allocated for that specific deployment).

Thanks,
