Usually the app/game will just continue using the location it has always been using if it doesn't use the new location. It really depends on how the location was specified in the app/game. It shouldn't be a big issue though since you can always change the location in the app/game as needed, or just move the Documents folder back to default if too many issues.
For example:
"C:\Users\<username>\Documents" - Would most likely not use the new location.
"%UserProfile%\Documents" - Would use the new location.
Documents folder selected in This PC - Would use the new location.
