I'm in the Gale crater and on my way to the mission "Impact Crater" and trying to perform a out-of-mission scientific task: Atmosphere micro/scoop (see attached image). I've tried both instrument on the soil and rocks to no avail. Am I missing something? (The rover is a Large rover with all kinds of instruments).

I've also noticed that in some other out-of-mission scientific tasks which allowed using multiple instruments according to the on-screen indicator, only accepted one of them (e.g., an AXPS/Scoop only worked with Scoop).

(btw, version 0.8.247)
