This's happening probably due to the script conflict - both reversal and roomba scripts run 3:00 AM UTC as it was stated somewhere, but I've seen several times that Community removes a question at 3:...

Proposed Change to Community Deletion Criteria

I'm uncomfortable with the idea of a "good answer" to a "bad question". If the answer is good and useful it implies that the question is actually a good question too. It might be expressed badly or ...

What should I do if I find the answer to an old question of mine that was automatically deleted as abandoned?

It's better to pursue undeletion (with edits). Deletions are designed to be reversible. There's an "undelete" link right there, which implies that it's meant to be used when the problems that led to ...

Are rejected migrations ever automatically deleted from the destination site? Should they be?

Rejected migrations are locked, and the automatic deletion rules exclude locked questions. So rejected migration stubs are never deleted. This is bad because it leaves content around that might be ...

RemoveDeadQuestions should not apply to Meta posts

I agree; there's a big difference between +0/-15 and +10/-25 (or +100/-101). Controversial is not the same as uniformly rejected. Sometimes the controversy might not even be about the question ...

Vote invalidation script should undelete questions that were previously wrongly deleted

This is super-complicated. The proper solution here would be to ensure that automatic deletion gives votes time to "age" and be vetted by the fraud scripts before taking action. Update: For ...

Modify the 'has 1 or 0 comments' requirement for 'RemoveAbandonedQuestions' script

Why was this question with score of +2 deleted by Community?

The question had two downvotes on it as well, and was deleted when the score was 0. The downvotes were later invalidated due to some voting irregularities, which caused the score to rise back up to 2. ...

How should we handle questions that have been reposted after being deleted due to one downvote + SE's automated process to remove questions?

When Roomba deletes a question, does it always end up in the "deleted recent questions" list?
