Claiming HUT rewards and not receiving XP. It had happened to me at least 8 times now ranging from 500xp up to 15,000xp rewards.
Ideas
I've been playing this game forever and know how it works. Whatever you want to call it the little number at the top right that shows 4xx,xxx coins/xp whatever didn't go up. EVERY time those rewards get claimed, that number goes up however many coins/xp you are rewarded. Stop playing games, this is a glitch and continues to happen. It's happened again two more times TODAY! You and I both know there is also an animation that goes along with claiming those rewards or any time coins/xp are gained. If I sell an auction item while offline, guess what? I get an animation of those coins/xp being added to my account. That never happens in my video. I hit claim and got NOTHING.
