[[Reconstruction:Proto-Indo-European/dwóh₁: difference between revisions|etymtree for dwóh₁]]
Well, you could have looked at the edit histories of these pages and noticed that I had removed {{etymtree}}
two weeks ago, or notice that Template:etymtree/ine-pro/*dwóh₁ had been deleted two weeks ago when you recreated it. That notice of prior deletion should have been ample notice that something was up.
Dude, I'm not some kind of administrator. I just create entries or edit existing ones, which means checking the history before doing something is the last thing I do. I don't recall seeing any notice. And that's just one case you're talking about. I've created a bunch of other etymtrees without knowing they'll simply be deleted. Is it too much to be able to know specifically what I'm not supposed to do instead of just guessing "something was up"? This is not rocket science!
