Hmm... Haven't seen that behaviour. However, one of my seekers presented some annoying behaviour in my last game.
It warps into the system, activates the detect mines things. Gets the nearest mine in range, and then procedes into a wide turn, brushing up against the mine it just detected! I had to start microing it. There should really be some checking to make sure the scouts, at least, do not set off the mines they are trying to detect. To say nothing of the ships that come to destroy the detected mines.
