Do not know how was before (a few months earlier), but now I have noticed a slight harder buffing. I can see now 4 potential spots around the building for the (buff) touchdown. Most of cases it is top left corner and that will accept right away. But, depending on a location of the building on the island, can be elsewhere. This means I have to target a "sweetspot" or a buff won't be deployed or I have to hit one of 4 mentioned spots to find correct one...ty
