The annoying thing is that you don't technically need a "perfect roll" for your campaign, but without it you have to reach the end of two adventure zones without dying, even on survivor you might get killed by some jank and need to go again.
If you want to make it easier to find the manor event, use the remnant save guardian, it isn't updated but if you get Sunken Haunt, Butcher's Quarter or Cotton's Kiln with no "injectable" then it's likely the manor is there.

Guardian also backs up saves, so if you die you can use a backed up save and try again.
