While this has probably been covered before, I thought I'd ask this question since it just popped up for me.
In Runner's Companion there is a positive quality called Restricted Gear, which you can take three times. Each allows you to purchase an item up to Availability 20. At character creation. Yet, Missions seems to have the Availability 12 cap. So if you take this quality can you buy that rarer item, or do you have to purchase it later (which is the secondary option under the quality).
