BUG with helping clanmates after the update
I have noticed that "sometimes" when I start an upgrade all or some of the clanmates help do not register. Once my bar remained at 0/39 although I got all of the 39 possible help clicks from clan and another time I got 6/39 and it remained at that without increasing any further.
I tested it personally on my computer by launching 3 clan accounts to provide the help and none of their helps were registered to my main account. So, the BUG is confirmed existing.
