The only place where dirtbag terraforming really annoys me is on the
following map (Bridge) :
https://zero-k.info/Maps/Detail/18434 [FolsomDamDeluxeV4] ,
If you think about the unit dirtbag logically , Dirtbag dead > Dirt lies on the map > Dirt flies away through the wind?
So I think
mojjj suggestion is not so bad, but as
Presstabstart has already noted, I do not know how much power / CPU (or whatever) is needed or how the overall programming effort is....
To
Astran contribution:
If you just have a tremor this is certainly helpful, but to make extra one for an area ,then you can also flatten the terraform manually again (which is probably cheaper depending on the area) :D
