So getallstate says there are about 4 mosas on the map, so the spawners are *working* more or less. Problem is, I can't find the actual mosas. I've gone out into each corner of the map- and I assume they're the correct corners, because that's the places where the otherwise featureless depths start to have some texture- and I've not yet found one. They're listed as spacially separate from squids, and I *have* found the squids in the inner ring, so those are working and are discoverable, but not yet mosas...

What am I doing wrong?
