I aging my Wyvern Armor +12 to +13 7/12/2020 around 1:50 AM (UTC+7:00). When I press + button, "Connection with the server lost" pop up has shown. And, I log in to the game again. And I see, my Wyvern Armor was lost. I never met this problem so, I didn't take a screenshot, and the game close so fast, around 2-3 second after the game shown that pop up. please help me.
