I'm trying to add a new set of Trading Posts to my mod for the Venetians. I removed the Venetians from the list in MERCHANT and added them to VEN_MERCHANT (the new building) and did virtually everything I could to emulate a trader's post, to include making new bifs and adding the descriptions. However, when I play, the Venetian Trading Post (and upgrades) say in the building info "Income gained from trade: 0" or something similar, but the total is always zero no matter how many ships I place and no matter how many trade lanes I connect (it shouldnt even be zero since it should trade with neighboring lands).
I've also noticed that if I give it LEV1_INCOME or something similar, it still will give no income. It'll just sit there like a Muster Field, drawing flies.
What, exactly, are the steps required to make a brand new Trading Post (with upgrades)? This is most likely the final thing I need to do, other than include the factions in the High and Late era, before I can release my mod as a playable version.
