A new bug?
 

I've never stumbled on this one before, playing with BSM 1.9 and after the bushwack mission I can't access merchant's inventory or loot crates. Anyone else run across this?

Just ran into this again, this time after rescuing the trader when his convoy was attacked. It's really odd, when you click the trade option in the dialog screen with any merchant, it just acts as though you'd terminated the conversation.
