The recent Diablo 2 Resurrected patch that was released a couple of days ago only to rolled back after an issue where the shared would not show is now back.
In a blue post this evening, the shared stash has been confirmed as fixed and all the other changes should now be back too, including the Terror Zone messaging fixes.A new backend fix has been implemented to resolve the stash issues and to reinstate the original change log from the OP in this thread.[/sc]
You may now resume with everything back in working order. Huzzah!
