An update to fix the elephant in the room that currently resides on official servers. Undermeshing. There are very specific locations on both maps where under-mesh bases can be built. They cannot be built anywhere, only in specific locations.
On the Exiled lands, it is underneath the “corkscrew” trees and the little circular stone towers in the highlands. On Siptah, it is underneath caves. There is one exception on each map, but you already know where those are.
In my opinion, the simplest solution is to remove the ‘falling through the world’ mechanic to allow players the ability to get under the map without dying. This will allow them to get to the cheaters’ base and destroy it. You will still have the ‘no building in a collision’ mechanic in play. So the under-mesh locations will remain unchanged.
There are other things that should be in the update as well, you probably have a list of them.
