Sometime in the past month (maybe with the new optitest thingy, I dont know), the evil of the disapearing trees at 1500 feet has been corrected!
***see original issue here*** I can now spot an enemy GV, and keep my eyes on his ground position while I climb up and around to drop my eggs. For a long time, the visuals of the ground 'popped' at ~1500' so the treeline or hedge clump the GV was near literally disapeared (and was replaced by an apparently randome texure patern) and it was nearly impossible to maintain a fix on GVs.
Thank you HT for making the attack run useful again!
