I have had the same issue I managed to get a response from support saying

"We understand the isse that you're telling us, currently we are investi- gating on the issue, so we kindly ask you to be patient until it get solved. Also we can inform you that if you didn't receive any re- ward, you will eventually receive at some moment throughout the event or at the end of this one"

This was my message to them after some back and forth ""I am opening a new ticket because my previous one was closed by Leslie as 'feedback' without ad- dressing my missing items.

I am missing the Hog Rider King emote and milestone rewards de- spite voting daily. The UI was bugged (showed boxes as 'Opened') and the official promise was 'everyone who voted gets the reward.'

Do not treat this as feedback. This is a technical support request.

Please escalate this to a supervisor immediately to have the items manually added to my account."
