Fairly sure this is the issue I came here to add. Playing DW20 1.21 pack. The 3 sizes of "hills" are shown on the crafted twilight map but there is flat ground with a few stone pillars sticking up in a kind on circular area where the mounds should be.

Update - Just noticed the igloos are also not generating above ground.....the spawner is there and a few of the smaller yeti. In fact all above surface seems missing .... the Hydra lair is flat as well.
