Custom github package tries to checkout old revision?

I made a custom package and put it on github. Everything was working fine until I combined all commits to one and did a force push. Now when I add my custom package I get the following error indicating it tries to checkout one of the merged, no longer existing, commits. I reimported my project, restarted my machine, cleared global cache and waited 12+ hours to let any backend processes complete, but I still get the same error. Any ideas? Even when making the repository private I get this error, so I guess its still cached somewhere…
