Campaigj checkpoints not working?

I decided to just play theough the campaign for fun. But checkpoints aren’t working. Like of o die they work. But when i save and quit, it restarts the level. Any way to fix this? Dont feel like playing the entire level at a time

Do you have the iron skull on?

Nope, brand new file and checkpoints just dont work

Oof, sounds like a bug. May want to send a ticket out and/or tag 343support on twitter.

Ehh shrugs whatever. I imagine it will work when replay and coop is added. Planning to replay for chivos as well anyway so
