Board didn't save

I made a new board on the same campaign as another board. I spent hours working on it, I remember clicking to push the save and saw the “no unsaved changes”. I reopened talespire the last edited for the campaign was well before I’d started that board. Opening the campaign I couldn’t find the board.

I’ve since remade a similar board as I was tracing a module map, but it’s rather disheartening and aggravating.
