This is a classic project management decision: You discover an expensive to fix issue late in the game. Do you: a) Pick a cheap quick but possibly insufficient solution, or b) Pick a reliable solution that costs so much more time that stuff downstream of your project (Artemis 3 in this case) can't use the results of your project anymore If the quicker fix doesn't, then you are really screwed. You didn't start the slow expensive fix, you have less money, and you may be out of time.
