Okay. I patched it up (over the others without a reinstall, is that okay?) and reverted to a save game where Versidus(sp) wasn't blackened out (ended up that a reload showed that both quick saves were currupt). After reverting to a checkpoint save (which was from 1.33a), the Versidus map was still cleared, and I haven't had any other problems with the black map. Am I in the clear, now? Or is there still a chance that the file is currupt, and sooner or later the problem will catch up with me again?

Thanks, again!
