[opensuse-buildservice] openSUSE:11.4:Update repository

Hello, I build against openSUSE:11.4:Update repository. My packages were just fine, but before a few days they got rebuilt and now in the build log, I see that the build process picks dependencies from openSUSE:11.4, instead of from openSUSE:11.4:Update. I tried to trigger rebuild manually, but the same happens - the dependencies are picked from openSUSE:11.4, instead of from openSUSE:11.4:Update. Is this some expected (temporal?) behavior or something is going wrong? Please, help. Best regards, Todor
