The title says most of it all. There are various floating H-Barriers in the outpost North West of Drimea (in the map Altis).
This is by far more prevalent on the H-Barriers more to the West/North West side of this said outpost.

IMO this could be solved by two ways (or a bit of a combination of both): either slightly moving this outpost EAST (enough so that the Western H-Barriers stop floating. But also NOT TOO MUCH, so that the Eastern H-Barriers don't start to float themselves). Or to slightly elevate the terrain under the floating H-Barriers (and to some extent also fences) so that the ground touches the bottom of the H-Barriers.
