Is this post up to date still? I notice in the list of crew bonuses that a couple are different that what is posted in the wiki. There are two differences I have spotted as listed below.
Here - Zenith: +1 crit underworld trading, +15 eff Treasure hunting
Wiki - Zenith: +1 Underworld Trading . +15 Investigation
Here - Guss Tuno: +10 eff underworld trading, +2 crit investigation
Wiki - Guss Tuno : +2 Treasure Hunting , +10 Archaeology
instead. Not quite as detailed but gets the point across and it is current.
