Lost Gems from Arenaand not from lossing a fight

Dear Tynon
Hello i have complaint to report to you. I was in the arena and a 100 Gems came up for me :) i was so excited to see it. so i clicked on it and stayed there to defend it. Yahoo i got through and won the prize.
so i went to Banshie cerb to start the fight on the world boss. when it crashed on me :(
i refreshed the game and wow my winnings of 100 Gems was gone.
Could you please get back to me on this matter. it's a bit unfair to have these winnings you give us to disappear from our game.
Yours Truly.

Same problem for me today, exactly. On server 1. My name is Johngalt. Please return my gems?
Thanks!
