I’ve spent a morning updating my condo.
Unfortunately, for no apparent reason, it didn’t save in the steam cloud.
Now, the issue solved by itself. Newly added items save in the condo as usual.
But for a few times that I’ve tried this morning, it just didn’t save on the cloud for whatever reason.
I was connected to the internet the whole time.
Items numbers in condo : over 8700
During that non-saving moment, items would perfectly save in other condos with less items in them.
The issue apparently solved by itself when I saved a snapshot, and loaded it.
