I remember reading it before when I was researching the problem. I read the link in the first post of the topside mod. It happens in the the Red Rocket molerat den (later in the game), Shamrock Taphouse, part of the tunnels in Vault 88, the Secret Vault 81, and Mulligans Mine Ride. What happens is that in interior cells that have molerats or bloodbugs, You can enter the cell, but you cannot save (ctd) within it and you cannot exit it (ctd).
Besides, the surging molerat bug is only one problem caused by SE. So, if Scrap Everything causes the bug, it is better to give up SE. I hear my old photography professor telling us that the best way to deal with retouching a photo is to do take it with rigorous care in the first place.
I haven't tried it to see if it fixes the bug. Click to expand.Others have suggested it.
