Description

I have created a mirror repository from Github. When I go the the panel "Releases", all tags are show with the right commit Id. But when I create a release on an existing tag, the commit Id is not the same and not match any commit Id of the repository.

Gitea mirror: https://try.gitea.io/zero-x-baadf00d/play-ebean-httpquery
Origin: https://github.com/0xbaadf00d/play-ebean-httpquery/tags
