AMI Not Found

My daily error logs have had this line, every 5 minutes:

00:50:11 - EC2:Launching EC2 instance. Region: us-east-1, AMI: ami-e1a1d1f7, error: The image id ‘[ami-e1a1d1f7]’ does not exist

I tried to manually search that AMI and I cannot find it. I am using the Server AMI and have done no manual configurations.
I found this AMI here
But it does not seem to be a valid AMI in us-east-1. Was this AMI updated/changed?

Any ideas what the issue is?

It looks like it should be ami-ec9bba97? I will change in /settings/ec2_locations.ini and see if I am going in the right direction.
