I tried to host a LAN game on my Windows 10 laptop, then use my iPad to join. Can't get this body guard achievement on my iPad (same gamertag). I realized a user can only get some achievement if he/she's hosting that game on that device.
I also testify that this is a valid and annoying bug when the game's set to Traditional Chinese, Simplified Chinese and Japanese language.
the game UI is full of text with virtually all punctuation characters half-"backspaced"-eaten by the following text.
However, when the game's set to Korean the punctuation characters seem to occupy the correct width.
I vote yes to this bug report.

[affects Win 10 version and iOS version]
Confirmed again using a new Xbox account on my iPhone version 0.15.4. The achievement notification is still unreadable.
