If you have not paid your unit since before the bonus took effect, you will still have to give them the pay they accrued before then.
When should the bonus take effect actually?
In Fallangard we already lost one region and two more are affected, yet no reduced unit costs.
Brutus payed his men every day since the first cold took grip of tota.
I also noticed some odd migration, perhaps intentional.
But peasants fleeing from the cold en mass in neighbouring regions only.
Once there they only emigrate further due to over population.
But this is usually about 30 peasants in total(daily), while between 5000 and 8000 peasants keep coming in(also daily).
It also looks like all peasants who don't flee in time are lost(died).
Also, will regions receive more income from all these new immigrants?
