While using the learning helper you are unable to progress if you have a colonist incapable of violence as one of the steps is to equip all colonists with weapons. Unfortunately colonists incapable of violence refuse to even hold weapons and I have been unable to find a workaround (unless I'm missing something obvious)
I only noticed this as my girlfriend recently bought the game and became so frustrated at this that she stopped playing altogether after only 15 minutes.
This is a known issue that is already fixed for v.1.0.
Thanks for reporting it though all the same.
