Re: [CURRENT ISSUE] Codes instead of text/ Blank text and bubbles

Have you tried recreating the The Sims 4 folder in your documents? I would rename your old one, restart the game, a new one will populate, and then try the game out before moving any old save files or anything into the new one. That will let you know if the problem lies in the game itself, or in your save files or somewhere in that old TS4 folder.

That usually fixes the issue. If you find that the issue is fixed, you can then try moving your old save files into that new folder, and see if the issue persists from there.
