I can let it go when you say people talking wouldn't be stealthy, I can let it go when you say using computers isn't stealthy- but how can looking at a Rock Pile make you immediately break stealth?
When you engage in a "conversation" with a Rock Pile, nearby enemies are immediately made aware of your presence.
I want to make it clear- this isn't after you choose to climb over the Rock Pile, which could be noisy, this is after you simply take a look at them.
