I'm really confused regarding this post I answered yesterday: Is it safe to wash meat packaging before throwing it away? The question was previously worded as Disposing of meat packaging, and its contents were asking what was the recommended way to dispose meat packaging.
I gave an answer which got upvoted. But while I was away, the question got edited drastically that completely invalided my answer. My invalidated answer was just sitting there for 11 hours, without any disclaimer that my post used to answer the question. (There used to be another answer along with the three remaining ones, but it's gone now.)
At first I thought that surly the edit was made by the OP, who just might not be familiar with how things work in Stack Exchange. So I rolled back the edit, and politely asked them not to make edits that invalidates answer in the future.
But later to my surprise, it was a mod who made the edit. I didn't want to defy a mod's decision, so I had no choice but to make another rollback to the mod's revision and edit a disclaimer into my answer (which, BTW, received downvotes while I away and unaware of the edit).
But up until now I'm thinking: Edits that invalidates answers aren't allowed, see Change to question invalidates my answer, what to do? Of course, if there was something problematic about the question to begin with, then drastic edits might be okay... but there was nothing wrong with asking how to dispose of meat packaging.
The mod did add an explanation along with their edit:
changed wording since the answers to the original went into a discussion on recycling
I agree that a discussion on recycling began, but it didn't or shouldn't have anything to do with the question; it was a completely valid question. To be honest, it appeared to me that the discussion was started and continued by one of the many answerers.
Can we please not do this to fellow answerers? At least add a disclaimer to the question, or even to the answers that will be invalidated?
