No worries, that check was to see if the brush is attached. It’s definitely not if none of those maps are there. It just helps us inform our next move.
So I’ve never seen this occurrence so this is going to be a bit trial and error trying to get the brush reapplied. So open up your landscape mode, and go over to sculpt and blueprint mode. It should have a layer called water, and once you click that layer is there an entry for the landscape_WaterBrushManager like mine?
