In a shared board with lots of lists, and which I always keep open in a browser tab across restarts, I suddenly found two lists with their titles swapped. At first I thought it was a Trello bug and thought of reporting it. Then I realized they would certainly get right back at me saying it's probably a prank of a coworker (even though they're not the type to do so) and scrapped that plan.
Then I went to edit the titles back, but as soon as I clicked the titles to edit them, the correct titles would pop up, and when I clicked elsewhere to cancel editing, the correct titles stayed, and everything is fixed. So this must be a bug after all, related to a stale browser cookie or something?
Has anyone else ever had this?
