Issue #25661: Mole Rats in vaults 88 and 81

My knowledge doesn't allow me to be 100% sure that what I'm reporting is relevant. So, if it's not, and if I'm wrong, feel free to tell me.

As I reported on the nexus forum, my problem was in the Vault 88, during the quest "Explore Vault 88". I was having a guaranteed freeze when I started shooting at the mole rats in the north-east sector. I just couldn't get around it. I noticed in FO4Edit that some ambush mole rats were missing their activator (DefaultActivateSelfTrigger). Then in the CK, I realized these activators were in fact assigned to ambush furnitures, instead of NPCs. So, I reverted to a prior save, and tried a homemade fix (below). Afterward, I've been able to clear the whole vault three times without a freeze. But I haven't been playing since. And as I said, there is no way for me to be sure that what I did was the right thing, and that I didn't mess up something else.

- I removed the "activate parent refs" for the problematic furnitures (xx00473C, xx0047A1, and xx00479D)
- then added the "activate parent refs" to the NPCs who were missing it: - NPC xx004A0B (ghoul): added activator xx004A09
- NPC xx00473B (mole rat): added activator xx004737
- NPC xx0047A0 (mole rat): added activator xx00479C

As for the (secret) Vault 81, someone sent me a message, reporting the same problem during "A Hole in The Wall" quest. Personally, I didn't experience freeze down there like in Vault 88. But I remember having a hiccup with this quest. There was no way for me to talk to Curie, at the end of the quest. Like if there were still mole rats to kill, even if there was none to be found. I had to reload 2 or 3 times to get around this. Strangely, the same "missing activators" pattern can be found there (below).

- mole rats 0011354A and 0011354D: are missing the activator 000DB0BA as an "activate parent ref"
- mole rat 000B0F01: is missing the activator 000B0F04 as an "activate parent ref"

Can confirm this issue in my game as well. I get it in Curies hidden vault, the Taphouse, the cave by Red Rocket and in Vault 88. Anywhere in fact that that mole rats spawn in an interior location on a trigger. Usually running through the area in tdetect so they don't aggro on me enables me to get past the issue. Should mention that I have been playing since the game released and the issue only began in mid 2018.

Just to add - as I forgot to last time I commented - this issue also occurs in the Vim Pop Factory on Far Harbor and also the Bloodworms inside Mad Mulligans Mine in Nuka World get the same problem (probably use the same scripts and triggers as the molerats do).
Again all interior locations.
There is a discussion about this bug here

Having this issue as well. I did not have a problem in the Taphouse.

I did manage to complete the quest by disabling the AI, re-enabling at curie, then leaving, however I encountered crashes in the normal side of the vault in consistent areas (hallway leading to the stairs to the basement, and above the clinic). Teleported out after recruiting Curie (to Sanctuary) and now the game crashes about a minute or two after loading. without moving, every time. Not sure if this helps narrow things down. Important to note I did the beginning of the secret vault normally. Right when I got to the big molerat problems started when you first see him in the hallway.

Someone claims that Sim Settlements might be a cause of this issue. It wouldn't really surprise if too many scripts running at the same time in areas that are already taxing on the game engine does cause the game to crash, but since I don't use it I don't know whether that's true or not. Either way, I've been unable to reproduce any crashing in any of the circumstances mentioned in the comments above when playing the game with only the patch installed.

I haven't been playing for a while, but I just wanted to say that I never had "Sim Settlements" in my load order. I've never used it.

I have a pretty light load order, and when I encountered my problem in Vault 88, I was near the end of my playthrough (level 95), with only the DLCs to complete. And I've never had problems with mole rats anywhere else. My game has been pretty bug-free the whole time. People seem to have this issue in Nuka World, but I haven't been there yet.

The fix I posted in the opening didn't fix my issue. It clearly fixed the freeze issue, I could then shoot all the mole rats and clear the whole vault without problems, multiple times. The game was not freezing anymore when the fight started. But when I came back to the game, I realized I was stuck down there afterward. Saving, or exiting Vault 88 resulted in a freeze (again). I had to use the "killall" console command to be able to get out. I still think those triggers wrongly assigned to the furniture boxes (instead of the mole rats themselves) are somewhat problematic. And since these furnitures are persistent records, I guess only a new game could tell me if that's the case indeed. But I don't have time to play this game a second time.
