Ok, I have had now four VERY suspect games during these last three days. In these games I was playing a predator, and the fire team seemed to know where I was immediately after I arrived to the area (within rendering distance I guess) despite being cloaked. In first three games I was spotted near instantly despite being cloaked, and chased around the map for many minutes with the fire team ignoring objectives completely, repeatedly spotting me regardless of my attempts to shake them and being in cloak the entire time (I have the perk that reduces cost of cloak).
What finally triggered me to write this post was this last game, where same happened but I was NOT EVEN SPOTTED. No “spotted” text came up, instead the fire team just opened fire in my direction even though I had been cloaked the entire time during my approach. They also climbed to the roof of the trainyard buildings to get to me.
After I ran away, healed, came back so that a big building was between me and them, leaped to the roof, then rounded the corner stealthed and in crouch to see them - INSTANTLY SPOTTED.
I am of the opinion that there is some kind of wallhack cheat or an exploit going on.
