Playing on Switch 1. Single player, solo self-found.
Roughly 48 hours ago opened the 3 portals for Ubers, defeated the 3 mini-ubers, opened the 4th portal. Attempted to enter portal, on load screen D2R crashed. Game had to fully re-boot. When I logged back in, it’s a fresh game. No portals. Keys all used. Uber materials used.
Today, collected a fresh set of keys, had 3 on me - 6 on mule. Swapped to the mule, moved the 6 keys to shared stash. I believe I didn’t save and quit the game. Used the home screen button to return to Switch 1 home screen. Closed D2R (Was hoping if I pre-emptively closed the game and launched a fresh instance, I wouldn’t repeat the previous crash issue)
When I logged in again, the 6 keys I’d moved to my shared stash weren’t in the stash. They aren’t on the mule either.
Feeling like the Ubers really don’t want me to have another Torch right now. 
Playing on a level 85 Smite Paladin with 4 successful previous torch runs. Three new items for this run were a Kira’s Guardian socketed with an Um rune, Gore Riders, and a Wisp Projector with the Oak Sage summoned. I’d summoned the Oak Sage for the Duriel Uber and it had died, hadn’t re-summoned it until just before entering the 4th portal.
All other gear had been used previously on non-crashing runs.
