When playing in a system not configured in English (using Portuguese in my case), some graphical bugs may happen, such as water in villages not rendering.

This problem also happens in Windows and, in Proton, can be fixed by adding the following to the game's launch options:

LANG="en_US.UTF-8" LC_ALL="en_US.UTF-8" %command%

Note: This also applies for the other Pixel Remaster games.
