If I am running on a world and I accidentally misclick "Save and Quit to Title" instead of "Options..." does that invalidate the run (I am playing with atum so it auto generates a new run). I've done it a couple times in runs that aren't my PB and am worried about if I accidentally do it in a PB if it would make it invalid. So far what I've done is just instantly quit the newly generated the world by stopping the resets and go to the previous run through the Single Player menu. Would that still be valid? Thanks in advance!

it invalidates the run, the rules say "Use only one world"

if you instantly join the world back it may be concidered for verification
