Since you need to order your villagers to give birth you can make them follow you and also build an outpost in front of the Chaos cave in order to give birth... that said I haven't noticed a Level raise from children born in different areas of the map.
native villagers get higher leveled with more distance from the starting camp... tamed ones not.
The childrens Level seem to be dependent of the Parents Level... had a Level 1.000.000 Female and a Level 300 MC had a kid and it was Level 50... if the mother is below MCs Level the offspring has a lower Level.
Offspring level is supposed to scale according to how north of the map they are born (and slightly to the east/west), not by parents' level. Highest possible level should be around Level 75 on the island, but this can be gotten around by sailing north and putting the delivery bed on the raft. Northernwestmost and Northerneastmost point on the sea should give around Level 95, and going out beyond the boundaries of the map can give a maximum of 105, at least from what I heard last time on JP wikis/forums.
Is it better to create one house with wooden beds or just many native tents and leaf beds spread all around an area? Does the bed even influence morale at all?
If two natives want to have sex but there aren't any beds nearby (inside or outside houses) to do the deed, they take a moral(e) hit.
If a native sleeps in a bed in a house until dawn, they gain a significant moral boost.
Not being able to sleep doesn't ding moral. You just forgo the bonus.
So if you can somehow make sure they don't suffer moral losses, you can forgo beds entirely...
I seem to notice bed allocation is limited to the first house they see in their territory, so with lots of friends I'd have to get... creative with territory/food box/well placement.
Still trying to find a good way to scale a settlement with the territory limitations.
Turn off Allow Love under the NPC status, don't bother with buggy house assignments. Done.
This might not necessarily work if they have already formed relationships with lovers and hated rivals, so you want to turn off Allow Love as soon as possible except for a model native settlement you might want somewhere to watch more emergent/natural relationships.
But for
Japanese black companies slave plantations resource production bases where you want to cram in as many people as possible in a limited area to maximize efficiency? Turn that HOT MESS OF A RELATIONSHIP SYSTEM off.
