During the Terra Inconita Challenge, the Fame in the cultural wonder pop up is displayed wrong and doesn’t take into account the transcend/nuclear fame bonus

It is counted correctly though.

I Couldn't reproduce it consistently but it happened quite often. Reloading a save seems to temporary alleviate the issue. ( the number will display 100; so it's still not counting the fame bonus)
I didn't check if it was the same on a regular playthrough.
