I accidentally made an article that I didn't want, and every time I delete it, either through its edit page or on the article page, it appears to be deleted until I refresh. I verified that I could delete other other articles.
I am unsure How to reproduce this bug. I accidentally inserted the content into the title, so maybe a too long title?
That is possible - Changing the title to something significantly smaller will unblock the article for deletion. Let me know if you need further help
