Trading commanders, exploit or not?

[Ink]

I think you're in the wrong thread with that.

I really want to know though. I once had a situation where I was almost certain that Pan had those unrest causing sneaking units in a couple of provinces of mine, but despite patrolling with _hundreds_ of soldiers for almost ten turns, I never found a thing.

Is this exploit something whereby sneaking units cannot be found? If that is so, I would certainly call it an exploit, especially for an unrest causing unit.
