"checkpoint passed" is greyed out. Do I need more bonus skills?
the first "checkpoint passed" is greyed out. I expected it to be filled in with a color eventually, but that hasnt happened. The only thing I have left to do is complete a third "bonus skill", but there are only 2 available for me to purchase, and i've already completed those.
Do I actually need a 3rd one to get passed the checkpoint?
Is the checkpoint normally greyed out?
Do I need to earn more lingots and unlock something else to buy to complete the 3rd bonus skill and thus the checkpoint?
Surely, other people have the same question. This piece is very non-intuitive.
By the way, once you get past a checkpoint, it always turns gray and says "Checkpoint Passed".
Before you pass it, it is colorful and asks you if you want to try to test out of a bunch of skills. Once you complete all the skills, there is no point to taking a test so it turns grey and says you have passed it.
