Right, that's the way it works. Commercial buildings don't add to the population when you build them and don't reduce population when they are removed.I've reached pop limit and if I remove a commercial building, it won't reduce the pop count... It only works with residencial buildings.
When you sell you will need to repurchase them later when you have sufficient population.@ Cosmic Blue, thank you I will try this and I hope it work for me. Do I sell them? Will I be able to get them back or will I have to buy them back?
