I think I somehow fvcked autobuilder once up, with such behaviour. I cannot remember exactly but something with uploading the same package twice as I did not get any feedback. I uploaded exactly the same files but autobuilder created somehow different sizes of deb files. So first created DEB was in repo and second one's size. That IS a mismatch. Only solution would be a manual intervention by repo admin. Or more easily iDont increase the build number and upload it once more.
