Because of the very helpful reply I got from sending in a ticket, and I think I saw no one talking about this yet, I have no choice but to sign up for an account.
My campaign tasks are having ZERO progress. This is despite having completed many battles, more than enough to complete 100 stars.
p.s. Reply from ticket: “Our support team is best at helping players with technical, account and other issues, so although we will read your bug report and pass it on to our development team, we won’t respond to bug reports here.”
edit: finally figured out how to attach screenshots.
