"Luxury containers are worth twice the number of luxury containers that a player collects, so one luxury container is worth 2, two containers are worth 8, three are worth 18, and so on."
What is that supposed to mean? 2x2 = 4, not 8. What the hell?
No, each luxury container is worth twice the number of luxury containers.
If I have 2 of them, EACH one is worth twice the total, or 2x2=4 EACH. Two of them would therefore be worth 8 in total.
