Palmyra Errata

The English translation in the rule booklet said you had 3 options on each
turn :

1) pass
2) buy/sell 2 amphoras of one commodity
3) buy/sell 1 amphora of each of the 3 commodities

Option 3 seems to imply that you had to buy/sell exactly three commodities
(one of each). This is wrong, you may buy/sell up to one of each commodity
(i.e. at most one of each of the three commodities).
