I know that you had understood it at the time of your posting already, and I understand the frustration when coming from a different expectation. But you said "I don't know how I feel about it" (the "free" expansion), and I tried to
emphasize the points (again) that could give you back the "being pleased about it"-feeling
BTW, another thought is: it
might be that there is another
technical dependency in their program, which wouldn't allow - not so easily anyway - to "ignore" the population the same way as coins/the price. And it was so "clear" to them, that no-one had the idea even of mentioning it. (had a similar situation and discussion with Playrix about the Gold Pass losing its rewards for other members completely, when the Owner switches between Coops)
