I had a faction at -51 and thought I'd spend some silver to improve relations. I paid a few times to get it up to -15, then invited them to send a caravan. So I'm out 900+600 silver, but figured the invite, then doing business with them might improve relations even more. They said they'd send the trade caravan in a few days, but it never came. What gives?
Am I just a stupid pawn for trusting that if I sent the money, even though they're slightly negative, they'd actually live up to their promise?
So now, I'm completely out of Neutromine and Components, and haven't seen traders in like a year. I installed the orbital trading station and had only a single f'ing ship in several years. My colonists are screwed when stuff starts breaking :-(.
Trade caravans don't show up if it's above 45C or below -40C when they are supposed to arrive.
I'm in a temperate climate. There has not been a heat wave in about a year., and cold snaps don't get that far below 0 :-). That's not it...
Had the same problem
