Can?t upgrade house of luck to level 2 in chapter 2

There may be a bug in my game as I am on the final step of chapter 2 and I cannot upgrade the house of luck to level 2, so cannot progress and will lose a whole weekend at least. My wifi was a little weak as I moved between floors/wifi points and may have caused a glitch. Please fix soon, currently I notice my last support ticket is still unanswered from a week ago so if this is not fixed by today, I will be unable to complete the event. Thanks.

Thanks, fixed now.
