Stolen Gems

I defeated Yendor for 100 gem stake. Less than 1 min before timer was over he defeated me and took them bakc. I reattacked and refreshed browser I had won gems back . It flashed 000 and I claimed then chest appeared saw 50 gems won and go to area it shows how many you have. Window pops up failed to sync with server so refreshed again this is a comon problem and the gems were gone.

You only win 50% of the stake, if you attack someone else for their stakes in the arena. You get 50 and he gets 50.

If you have an allocated stake and defend it successfully for 30mins the whole stake is yours.
