# Why can a question be deleted (by non-moderator users) without being closed?

I noticed that this question: How to solve $$\ln t = t-1$$ to get $$t=1$$? was deleted by three users without even being closed. How could that happen? Is that a system bug?

Note：it was closed and deleted before, but it was reopened later by five users (including myself). Here is the timeline: https://math.stackexchange.com/posts/3146074/timeline

• Tangentially, the specific situation is a bit odd. A users vote to delete something only to vote to reopen it two minutes later... Maybe it was a just a clicking-error. – quid Apr 26 '19 at 20:20
