Blank Lessons Window popup (related to new expansion)?

Looks like this:

This occurred with all mods disabled. When I close the game, remove localthumb cache, and go back in, it's still blank like this in the lessons section.

For me the buttons had text on them. I didn't click them as I wanted to go into CAS first.
Maybe try repairing your game and see if the lessons show up after that.
If that doesn't work, try removing your mods folder entirely (even if in theory the effects would be the same as disabling mods).

My game is plagued by this. Every new interaction, aspiration, social app etc is missing the text on the button

I've done everything but uninstall and I'm guessing that's what I'll have to resort to as nothing else is working and no mod or cc cas/bb causes it

If you are seeing missing text it’s an issue with steam.

Here is the report for it so you can add more info if needed and me too the post
