If you create some boards, all can be deleted except the last one. If you try to delete the last one and hit Update, you get Request failed.
Request failed
Reproducer: 1. Go to Settings->Boards and create your first board 2. Refresh the project page, it shows up 3. Go to Settings->Boards, delete the board with a trash icon, hit Update, you'll get Request failed 4. Refresh the project page, the board is still up
Fun one :)

Just ran into this. Noticed the feature and started playing with it. Now I can't delete the test board I created.
