For what it is worth, I run into the same issue. Without WoTC I have a very stable game, with WoTC (which I freakin love BTW) I get serious crashing issues especially when i'm deep in the city between Goodneighbor and Old North Church (or whatever it is called where you meet the Railroad). I'm really hoping the new version will have fewer issues. NOTE: i suspect the real issue with the mod is between adding all the actors and trying to calculate all the conflict they are generating off screen (but still in the same zone) that our systems are simply choking on all the additional data. Further I'm wondering if that combination isn't creating some save bloat which contributes to the random crashes. Yes, this is what I am thinking as well. I made a tough decision to start over and remove WotC from my modlist. I've been wanting to create some large settlements using Sim Settlements and Horizon, and it's frustrating to have random crashes start occuring massively after putting in 24 hours into a playthrough. I replaced it with Faster Respawn Rates (3 hours, both settings) and hopefully the world doesn't seem completely dead. I'm really hoping that the new, revamped version will be a plug and play (which doesn't destroy saves) that I can add in once it's finished). It was a call between playing the game and not being able to play the game, sadly.
