[0.95] Cleared Scrapyards, but borders won't revert

It's all in the title. Cleared out the scrapyards and searched all around them for wandering monsters and found none. So far in 8 games the only place I've actually been able to clear and settle is the Arctic Wasteland. The twisted wildlands or whatever they're called haven't reverted in 3 different games I've played. Now I can add the Scrapyard to non-convertible. Kind of a bummer.
