I don't see anything about this in the rules or anywhere in this forum.

Is it allowed to save a game mid-run and then reload that save file later and complete it?

I suspect the answer is "no", but figured I would ask. Thank you!

IIRC it's frowned upon at least in the 100% category, because the achievements aren't bound to the save. But I'm not sure it's actually exploitable

in 100% reloads are forbidden
