TL;DR
Don't restrict the placement of BP from the map, as long as chunk has been revealed.What ?
Currently placing BP is limited to the area you can see or is revealed by radar, but radar ranges are quite minimal and thus remove the entire point of placing BP on the map.Why ?
The new update with placing blueprints on the map is a very good idea, but severly limited by the fact that you already need to have pre-existing radar coverage in the entire area you want to place something in.Which is often something you would want to use the blueprints for.
