gu15 WITHOUT dlc11:
and with dlc11 enabled:
not shown in screenshot but also similarly affected: old world goods such as beer and sewing machines
this is from a new world island with 4600 obreros (no jornaleros)
lifestyle needs are disabled (not that those should affect demand anyhow as i understand it)
loaded my last game from gu14 twice, one with dlc11 subsequently enabled and one not (so demand is identical to gu14)
EDIT:
enabled lifestyle needs on that island, demand of all 3 is also similarly increased by dlc11
EDIT:
NOT AFFECTED: all old world population tiers, all arctic population tiers, all enbesa population tiers, jornaleros
