The Scotts get a super useful building called Souterrain that eliminates winter attrition, produces food, and dramatically raises your replenishment.
Level 1: +50% replenishment
Level 2: +100% replenishment.
One problem: the replenishment either doesn't work or the math behind is deceptive.
I moved an army from one province with a level 2 Souterrain to another with a level 1 Souterrain and there was no noticeable uptick in replenishment. My army moved from one minor settlement to another minor settlement.
Anyone else notice this?
This is on VH campaign if that matters.
