@JaxSim1991 A feeder city is a 2nd city that serves to produce items to pass along to their primary city or club. Many folks will tell you that they are legal...they are not. That’s what EA’s contractor put in writing in a pm (but refuse to publish in the forum, go figure) - simply stated you can play multiple cities but they can not be used as a satellite or feeder city. This means your cities must be independent of each other with no “trades” between your cities or your mayors club members. An example of a satellite club was offered in this forum a couple of months ago when a mayor shared they met with mayors from another club(s) in a “dead” open club to trade war items...this is a clandestine activity but it has been ignored like many issues that they are very much aware of.
I shared with you the correct answer related to hamburger farming...what you do with it is up to you. Not everyone was participating when this was posted and the mayor who shared the finite answer was once again incorrect. I wouldn’t be terribly concerned if I was you if you choose to ignore what I shared...it’s obvious the contractor is unlikely to address this issue.
