How can I make WP_Query get posts that have a tag but also have random other tags?

Ignore this question, I’m not sure how or if I should delete it. My issue was that when I added multiple tags to my post, I separated them with spaces rather than commas, so it was interpreting it as one long tag which didn’t match the query tags.
