I had this bug, as well, though it seems to be working normally, now. Refreshing doesn't change a thing and I already have ABP (also turned it on and off to see if it changed anything, which it didn't).
I made a ticket and got the reply that they're working on this problem.
I do have a work around for those people who happens this to. I found this game originally on Agames.com and when I have the discussed bug, I don't have it when I play through Agames. Though I can't open a secondary tab, of course, as that gives the bug, again. ( I also noted this in my ticket)
I hope the team can find out what's wrong and get it to work again, I really do enjoy this game a lot
