Orthoimage not generated

I processed some drone images for the second time, since my files expired, but this time the orthoimage is blank https://www.mapsmadeeasy.com/maps/detail/6e611669ff3241cd99c8e2e50e529616/

I don't mind processing again but 1. I don't want that to happen again. 2. I would like to request a refund unless of course, it's my fault.

here's the URL https://www.mapsmadeeasy.com/maps/detail/6e611669ff3241cd99c8e2e50e529616/

Thanks!
