Had a panzr pop up in front of me between 200and 400yds - middle of a large clearing in the forest. He was completely invisible up until that close to me. This was an occasional problem for me in patch 2, now a persistant, continuous problem in patch3. GVs are visible at long ranges and extremely close ranges - can't see em in between.
