As of the most recent update last year (fixing cloud saves for non-English versions), the game now leaves multiple save folders for the Venice expansion, with only one containg the actual saves. This seems unnecessary, surely they can be consolidated into the one folder name regardless of language selected or have the single folder name changed to the corresponding language downloaded?

I've attached an image as an example.

YES! Omg this bothers me so much. Have you contacted support yet...? What did they say?
These folders keep reappearing and it really annoys me...

It's been a while, but I'm wondering if this issue remains.

Have you tried reaching out to support regarding this? I think I might myself.

I did not. I was waiting for a response here and pretty much stopped playing the game soon after.
