Hi, today morning (probably around midnight) Copr start using new version of mock, but Copr had one configuration option in place, which caused one ugly bug. As consequence all builds failed, but Copr mark them as successful. This issue is fixed now.
But if you wonder where are your packages from today morning, then it was my fault. Sorry. Deleting those builds (or bump up release) and resubmit, will fix it.
