I just realized that the history sections for the scabbard and sword will be exceedingly similar after the episode Rose's Scabbard. Since the scabbard always appears with the sword and doesn't really have a signifcant part after said episode, and the history section for the sword is up to date, this may be somewhat redundant.
Hey, I honestly wish they could put the nice work feedback button back, but I just wanted to express the great work you're doing right now, and helping update those history pages! It's a lot of work. Keep it up! Have a great day/night.
They took it out because it was an experiment to test out if they want to keep it or not, if you see this edit and this blog. If we want to provide feedback, we can contact wiki staff and see what they do.
