I notice that even if I can see stealthed opponents, I cannot target them. For example, I see a stealthed Lurker via his shadowy outline. If I go into Attack mode, the crosshairs will not recognize them. I have to physically bump into them before I can get a lock. My detection is very high, and I am stealthed also. Do I need to turn off my own stealth before they become attackable? I am looking at the Paranoia feat and the bonus against stealthed enemies seems useless given this issue.
