Game configurations: New game Sim Settlements Three-in-One v4.0.10 Sim Settlements - Conqueror v4.0.10 Workshop Framework v 1.1.6 No additional city plans. Only using optimized RotC plans. Only have settlements pre-built by Conqueror. Running on hardware that is more than capable of running Fallout 4. Papyrus memory settings are set in Fallout4Custom.ini. Issue: Some settlements consistently cause a crash when they are approached. The effected settlements in my current game are Graygarden and Oberland Station. Both are not yet conquered. Other large settlements (containing many objects) such as Starlight Drive-In and Outpost Zimonja load perfectly fine when approached. I've also tested while doing following: Disabling all add-on packs. Disabling all Sim Settlements performance options. Disabling multi-threading. All settlements in my game are pre-built by Conquer and use the optimized city plans included with RotC. I don't have any additional city plans installed. I haven't manually placed any additional objects in any city. I haven't increased the build limit for any city. I'm not using any other mod outside of the realm of Sim Settlements that effects settlements. I always thoroughly check for conflicts before committing to using a mod. No mod is conflicting with Sim Settlements or it's peer mods. The papyrus logs, as expected, don't provide any context for the crash.
