MythicalMysfitsCoreStack fails to deploy. keep getting a rollback-in-progress message. when i disabled rollback it says CREATE_FAILED.

Status Reason (MythicalMysfitsCoreStack):
The following resource(s) failed to create: [PrivateRouteTableOne, PrivateSubnetOne, PublicSubnetTwo, PrivateSubnetTwo, GatewayAttachement, PrivateRouteTableTwo, PublicSubnetOne, PublicRouteTable].

Status Reason(PrivateSubnetTwo):
Template error: Fn::Select cannot select nonexistent value at index 1

Status Reason(PublicSubnetTwo):
Template error: Fn::Select cannot select nonexistent value at index 1

Sorry you're getting this error. Were any values in core.yml altered? That template should create fine as-is without any changes required. Seprately, which region is this being run within? Be sure it's within one of the supported AWS regions called out in the beginning of module 1.

Hi, thanks for the response. No changes were made to the core.yml. I may have overlooked the region settings for the stack, which could be the problem. I will update this post when I check the region.
