So mildly irritating to say the least.
I fired up my Steam Deck to test performance.
Playing on the PC previously, I verified the Steam Cloud Sync was good - it was.
Verified Cloud Sync was good on the deck - it was.
Loaded into the game: didn’t show my realm
Closed the game on the Steam Deck > Ran it on PC > No save file
It wiped my file. Even checking the Steam Cloud Page, when I tried to pull the Realm file, it’s corrupt, listed as not found.
All to say: if you have a Steam Deck, it might be best to play on one device as of now, as I lost 7 hours of gameplay…so yea.
