Hello all, truth be told I don't actually know if this is a bug, or an intended feature. I took a break from the game for quite some time, but I'm back now!
Anyway, I was out on the Plains of Eidolon, using my hushed invisibility Loki build, doing some mining/fishing.
Literally all of the 'flying aircraft' enemy types knew exactly where I was, at all times, no matter what. My invisibilty lasts 36 seconds in this build, I have the Hushed Invisibility mod, and at no point did I fire a weapon or even take a single hostile action.
And yet, multiple dargyns, bolkors, etc, hounded me everywhere I went, unerringly shooting me. It didn't matter where I went or what I did, I could easily cover an entire kilometer (in silent invisibility), and flying squadrons of aircraft would follow me, expertly sniping my head.
Is this a new RADAR feature that flying enemies have? What's going on here? Stealth nerf to stealth frames, or what?
