Loaded a game after the daily reset that happened 47 minutes ago. I've had loading issues all over the site that lead to me having to manually refresh pages. I completed the 3rd level of "All Yours Stars Are Belong To Us: Create 250 3-Star pieces in Arena" during that run. I've been trying to farm my arena vouchers and I started the run at 236/250 of "We're Rich!: Obtain Arena Vouchers", and I ended at 236/250 despite ending in first. The match didn't give me the end screen of rewards, and it told me to refresh since it couldn't grab the data. Upon refreshing I was taken back to the main screen and didn't get my first place reward.

Further context, my arena tickets were at 306 at the start of the round and were still 306 at the end. It was all bots-- no other players.
