Mart: Major (and odd) bug report here.
Character Level: 11
Companions: Jericho and Charon.
Mods: FWE+WMK+MMM+FOIP (and yes I have the right .esps for WMK, from the FOIP, and yes I have all the FOIP patches)+Mez's Merged Patch + Kais fixes, tweaks, no ammo weight, and his armor fix.
No other mods.
Everytime I get near Project Purity, outdoors, (this is BEFORE broken steel...this is the FIRST trip there to look for signs of Dad)...I crash. Hard.
The first time, I approached from Rivet City side and got up onto the catwalk. I sniped two mutants, then started to duck walk to get close enough to snipe a third that was at the far end of the catwalk, by the door to enter the memorial.
At the *exact* spot where the location 'dinged' over from being 'aware' of where it is (box with a slash on your map) to having been 'visited' (fast travel enabled from then on), the game crashed.
Reloaded the save, now there were two floaters up there that weren't there before...sniped them...started to RUN this time, just wanting to get it overwith...EXACT spot...crashed again.
So, started testing...
I loaded up the same savegame again and did a MOVETOQT to get to the control room. No problem...two mutants...no biggie.
Cleared out the entire building...no problem.
Got to the exit back to the wilderness and (smartly) made several saves.
On exiting the door...INSTANT CRASH.
So, since MMM was the bottom stuff in my load order, I turned it all off first...CRASH GONE.
Turned MMM back on....CRASH IS BACK.
Kept MMM on, stayed inside and waited for TEN FULL days (since you said FWE's reset is at nine days)...STILL CRASH.
Removed MMM again...reloaded the save from after waiting ten days...CRASH GONE.
I'm mystified. This is the first game that I've had this happen to me, and I have no idea why it happened.
This spot, and Reillys Rangers vicinity are the only two spots I've had ANY crash problems that I can peg to MMM specifically, and I believe the Rangers area crash was mostly bad luck with spawns, since I somehow wound up with two Gargantuans, three behemoths and about 30 to 50 super mutants, not to mention a gaggle of night ghouls all running around fighting a BOS patrol (disabled that mod at that point).
Wish I could offer up more info, Mart, but since I can't even APPROACH project purity in my game with MMM on right now, I can't point the finger at any given critter spawn.
Its a hard crash to desktop, by the way.
The ONLY thing that stands out in my mind, is that I'm level 11. Other games I've played with MMM, I've either been under level 8, or over level 14 when I went there.
