theres no modern theme in chinese version

Many chinese users can not see the modern theme.

I find the solution myself:

Because I use Chinese as my phone language, due to a localization problem, there is no theme selection available in Chinese version; however, this achievement requires you to correctly flag 500 mines using modern theme, and garden theme doesn't count! So
I switched to English, reboot my phone, and played Microsoft Minesweeper using modern theme. In this condition, the counter works correctly and I already unlocked this achievement.

BTW, would you please still submit the feedback that theme switching is not working if system language is Chinese? This problem persists since the very first day of Microsoft Minesweeper's release on Windows 8 in 2012. Thank you very much!

People reported this problem to Microsoft Chinese support forum and Microsoft employees replied that the problem is under investigation. We can do nothing but wait for a future fix... Also, according to the posts in this forum, seems that people using languages
other than English and Chinese also have this problem.

Another problem that annoys me is that if the system language is set to Chinese, theme switching no longer works and you can only use garden theme. This problem persists since the very first day and still no fix. It is interesting that Microsoft used modern
theme screenshots in Chinese version marketplace, but user have no access to this theme. I guess the problem is caused by the localization work, since theme change is working in Microsoft Solitaire Collection and Microsoft Mahjong...

Modern theme not visible in italian version of 8.1 too

Chinese zombies!!! Just the theme for Halloween!
