Played now some games after a break, I have to say, the lost population is still annoying. I also think, losing population AND stopping growth while producing settlers is a bit too much. Iam also not sure why the production process of settlers have to be so strange. Not needing any food while generating settlers but getting more hammers if I would exceed the natural food consumption is such a strange, illogical process, that I would simply normalise the whole thing. While producing settlers, your people still consume food and your city can grow, but you will lose population if the settler is finished. An other thing could be also, that at the end of the process, you lose an increasing amount of food instead population, while the production cost stays the same.
