NOTE: This patch was applied to the backend and, as such, there is no new update in Steam for you to download.
Until now, there has been a nasty bug that affected published boards once they are imported into a campaign. If the state of objects (doors, chests, etc) were changed, but no tiles were added, moved, or removed, an entire region of the board could be lost.
With this fix, published boards are safe to use again.
If you have a board damaged by this bug, that copy of the board is not recoverable, but you can reimport the board from the published URL to recover the entire board.
Thanks to everyone who has been beta testing that feature and reporting the issues they found. It was instrumental in helping us reproduce, and ultimately tracking down, this bug.
On to the next bug!
