That's funny, but yeah I guess it's been 10 years and first post.
I just deleted the cache but no luck.
I assumed it was an unlisted hotkey I hit by accident, but if not I guess it's time to reinstall.
You're probably right on the corruption, since it happened right after I started a new game that was DOA. I set it to start in the future era with a lot of different options, and the game had an exclaimation mark (!) in the now-missing stat bar. I've never seen that before, and hovering didn't tell me what it was. I also couldn't select any building to build and couldn't end the turn. So I quit and this happened.
Any idea what the ! was?
Anyways, thanks.
