I know that production stops when you don't log into the game for xx days (not sure if 24 or 48 or whatever) but I thought building upgrades continued. In my case, they didn't. I went on hols for 10 days, didn't log in, set off loads of 7 days upgrades thinking it would all be done when I got back. Turns out, it wasn't. When I got back and logged in, I still had 5 days for all of them.
A member of my guild says this happened to him as well yet another says his upgraded while he was gone for 12 days. Did BB change something or did I hit a bug?
Thanks.
