Step to reproduce :
1. Playing in french (and maybe other languages)
2. Having Sphinx of Foresight in the opponent opening hand
3. At the begining of the first turn, the sphinx's ability triggers
4. The translation of the ability is missing, see image attached :)

I'm playing on Windows 10 Pro

Edit : I'm sorry, the upload of the image failed, maybe you have a maximum size but it's written nowhere :/
