I have only been playing this game for about two and a half months, but, I am pretty active at it. This morning, my neighborhood changed. I had 303 forge points invested in a neighbor's GB that was near returning me 145 forge points and over 5500 medals. I, also, had several smaller investments in neighbors GBs. All of this disappeared when the neighborhood changed. I didn't realize that was going to happen or I would have put up more fps to collect several of those GB investments. Is that how it works, whatever you have out there is just lost every two weeks?
