Hi there, sorry you’re experiencing difficulties. It feels like this post is a follow up to a previous one but I can’t find another one that you’ve made? We are working to fix these issues as quickly as we can. I’m assuming that you mean the items that were in your stash tabs are gone and not the actual tabs themselves.
I see that you were having some issues with character loading before. If those have been resolved, did your characters come back or did you have to start over again?
If it is a new character, I just need to check that it is in the same “league” so that’s HC vs SC and that you aren’t playing Solo Self Found as this will force a unique stash.
If you are loading in to an old character, did your crafting materials and gold also vanish? They are stored in a very similar method to the stash and should probably behave the same way.
If possible, getting you to submit your player.log file would be very helpful in attempting to solve the issue. More information on finding that can be found here: https://support.lastepochgame.com/article/39-the-games-log-file
Sorry, I know that was a bunch of questions, just gotta get that sweet sweet info.
