Looks like I was right in my predictions, there’s been other occurrences of this but this perfectly demonstrates the issue I was warning about, welcome to fragmentation. I note that this hasn’t been corrected by the mods yet and we’ll never know if it would have actually been corrected as the creation of this post will skew the data.
Again, as I mentioned above, it would be easier and more manageable to remove the locks and allow people to necro old posts for the betterment of the community as the small number of times this happened is trackable and manageable where as the current system demonstrably isn’t.
