No more Abyssal Overrun?

Since the new patch removed all icons besides bosses and unique map type icons, I haven't seen an Abyssal Overrun map. Am I just unlucky or was this an oversight when removing the inherent content from the maps? Anyone else happen upon this? I've only ventured w couple screen lengths into new territory but usually I would see at least one by now.

They just added the icon the th nmap legend, which is effectively useless after removing all of the icons, so I guess I'm just a bit confused
