Goodnight.
I have the devil 3 Reaper of souls, this afternoon I have been playing with the Necromancer (a very funny character!).
After dinner I went online to play with a friend in season 22 (which we have been playing for a few days).
FIRST FAILURE. When I connected I got a DLC failure! And he could not continue the campaign. I have exited the game and reloaded it. SECOND FAULT. Not only has the DLC stopped working, but also everything I had has been erased. When I started the game I loaded some data from years ago and I have lost EVERYTHING I HAD! Please a solution ??.
Most likely reason for missing / old heroes is that you might have logged into the wrong server region…
…and your up-to-date / well geared heroes are on the region you normally play on.
