Did JIRA/Atlassian update their request queue UI?

[Stuart Ross]

It went from from looking like a sleek modern thing to more of a legacy version, I just got spooked when it didnt look the same. Examples are how the status change and all those options to assign are in the top center rather than on the right.

I was busy testing my workflows when all of a sudden it changed its UI and layout, of course I reverted opted to change the workflow back to the default but it still looks like this now. Please tell me this isnt because I did something thru the workflows

Seems like you switched to the old issue view instead of the new. There might be an option to switch it again in the ... menu. Otherwise check your Jira preferences if they somehow switched to not wanting the new issue view.
