It also left alot of metal shaving behind in the cylinder (pic).

I am on my phone so I can't tell but it seems like the tip of the spark plug was stripped. This explains the metal shaving and why it took u forever to remove that plug.

In the future, use some anti-seize compound. Also...check the spark plug hole and see whether the thread is still good

I hope this helps. Good luck
