Misfire consequences

[Prime First]

What happens if a misfire goes ignored for a long period of time. Anything serious?

While the missfire is happening you will pump raw fuel into the combustion chamber, which in turn will ruin the catalytic converter.

Why would you continue to drive it like this anyway.

damage to the cat is about the only short term consequence.

Or all that raw fuel can contaminate the oil, cause lack of lubrication in the cylinder walls, foul plugs...who knows what else.
IMO: do not drive a car for long with a missfire. unless it's a real emergency.

depends on how much its missing.
