Maybe I'm newbee, but my PH is Lv 4, I can't upgrade my lvl 3 wall rows to lvl 4 even though, I have the gold and free architects to do the job. Is this a bug is there a limit for upgrading walls, because I don't get any message at all. When I press upgrade, nothing happens.
Is it because you need to upgrade your PH first? But it should give a message then. Can't remember what ph grants you what level of wall..
Thanks for your reply. I'm just making a new island~!! On my other ipad mini to see if this my device problem. Both devices are LTE.
I agree with Fish Eyed Pirate. I thought I was experiencing the same glitch with upgrading rows of walls. I then tried to upgrade one by one and that is when I saw that I can't upgrade them because they are max for my PH level. Check and make sure they aren't max already.
