Secondary islands not generating profits

[D3mux]

Hello, I don't know if I'm missing something... but after developing the first settlement, I colonized two other islands and built a few houses (<100 farmers, 12 houses x 8/10 inhabitants). I provided enough food (fish) and market connection is 100%. Still, these islands balances are negative, I see only expenses due to harbor, fishing and logging but houses do not generate any coin and this pushes down my global balance.
Is something wrong?
Thanks

Most coin comes from luxury items. If the island is all framers make sure they have a Pub, Schnapps, Etc. Check the Happiness tab to see these items and the amount of coin they generate. You may need more people to overcome your expenses. Or upgrade to Workers.

Well, if you had one island, best to get no more than 1,000 farmer with no overproduct or underproduct, product what farmer need, build only what you need to avoid royal tax, royal tax petty hurt that time, once you hit 1,000 farmer while look at Shift Q to see product demand and supply, get rid if overproduce, build more if need not met. Then forced on upgrade worker, you could hit 1,000 farmer and 1,000 Worker to avoid tax, but once you got worker product steel and farmer do wood, then go ahead find very good island (medium and large island and look at resource for future that your main island lack of, more oil is good investment in future as well, that is long term goal, once you get large/medium island, do same thing similar to your main island, but there is royal tax but cheaper than only one island with farmer and worker. Basic it's gave you discount of royal tax, more you take island (medium and large, not small because might not worth it or worth it, depend on space and resource on it, how far large island need those resource,) bigger discount of royal tax.

I would had couple medium and large island build and upgrade to City "artisans" but I put limited number of artisan, but forced on many farmer and worker as they don't need mines like iron mine, since iron mine and all kind of mine is very limited supply as Artisans is need those mine, but not your main island, your main island would forced on engineers and investors as you get those share workforce dock, all other medium and large island supply workforce of famer/worker/artisans to your main island while your main island forced on engineers and investors, you make lot of money even royal tax don't hurt much, but royal tax would be more better if engineers and investors more on other island in that same map, but not worth it due resource and space is kind of limited from that point.

Influence, space of island, high end resource like Brass or gold is your worry while you don't worry about money in end game. In early game influence, space, and resource is least of your worry while money is your main worry, but in the end of game it's other way rounds. money is your least of worry, but space of island, influence and high end resource (not farm and tree resource, it's mines mostly in limited supply is your major worry in late game. Had fun learning!

Thanks for your replies, the inhabitants had all the happiness and goods satisfied, still not generating income. Population wasn't high, I simply had "+0$" income in every house in the second and third islands.
I gave up and started a new sandbox map and guess what, now houses generate income... dunno if it was a bug, probably it was.
Thank you again.

That is wield. Glad it's working properly now. Happy building.

That is very odd, you should sent those old saved game to Ubisoft so they able to find what wrong and do bug fix so someone don't experience those bug in future, but ah well.
