Peoples edits aren't constantly rejected. Only when they violate policy of not confirming bugs on talk pages, or when they add speculation to articles.
You have no way of knowing who will do it & who will not. You mention a bug that got removed here. Let's go over why it was removed. You provided one source, UESP, however, when one checks the source, it's two posts about the bug & nothing more. Then you check the article itself, & it doesn't even have the bug on the page. You're asking this wiki to do something, that not even your source does, which baffles me.
& while were on the topic, you can see here, that they do the exact same thing for their bugs over there. & even say exactly what I have been saying here. Confirming bugs on pages make this community, & this wiki much more reliable & credible.
For Tombs idea, while it sounds good in theory, step one of that process will just be entirely skipped by 99% of all editors. People won't go through the trouble of reloading a save, & then doing it again. If anything, they will just say they did.
Lastly, we already tried this folks, it didn't work, we ended up having a bunch of unconfirmed bugs all over our articles for a long time. To which I might add, were transferred over to Bugs (Skyrim) which ending up being an extremlely long page full of unconfirmed bugs that became entirely impossible to even use. Moreover, several editors spent a long time cleaning up at the request of administrators such as Tomb here. We would literally only be repeating failed history once again for really no reason other then for the sake of it.
