Destroyed ec2 resources with count_tag and exact count

[Bill Brooks]

I am working with Ansible and just accidentally terminated 4 ec2 instances out of 20+ in AWS and I'm trying to figure out the why as to what was deleted.  I have already determined that the code I originally used was wrong, but wish to understand what happened.  The quasi code in question was/is:

- name: Create EC2

  ec2:

    key_name: key

    instance_type: t2.medium

    image: actual_amiID

    wait: yes

    region: us-east-1

    vpc_subnet_id: actual_subnetID

    instance_tags: { "Name":"vpc03VM01" }

    group_id: actual_securitygroupID

    count_tag:      (or count_tag: 1)

    exact_count: 1

I'm not 100% sure that count_tag was empty it may have been 1.  4 instances were destroyed, it tried to destroy a 5th, but it had protection.  All of them had some tags, only one of them had the Name tag in question, but two of the other ones were named similarly ( vpc01VM01 / vpc02VM01 ), the other three (including the one that wasn't destroyed because of protections) were named differently.  I want to understand why these instances were terminated and the one that I was trying to create wasn't created.  I was trying to use the count_tag and exact_count to be similar in functionality to "state: present."

I did some further testing and want to confirm that the count_tag setting I used was: 

count_tag: 1
