lol, that is quite the meltdown!
I’ve never done that, but I did make the mistake years ago of salvaging a bunch of BP items I wasn’t using, and then missing those items later.
At least you got a bunch of resources and/or coins that you can use to rebuild. I wouldn’t get my hopes up that they will reverse your own decision. It would get messy very quickly if they started doing that for players.
The nice thing about rebuilding your inventory is that you can be more picky, and avoid the items you never really liked.
