Problematic Mods

The following mods have issues in them that can mess with Sim Settlements.

Alternate Start Infinite Answer

This mod messes with the Workshops array. It will not only prevent Sim Settlements from working correctly in some settlements, but many other mods and features. This mod was discontinued and should no longer be used.

BS Defence

WORKS! Just make sure you are on the latest version.

Don't Call Me Settler

Can completely destroy your workshop system over time (doesn't happen to everyone, but I don't recommend risking it).

Enhanced Game Play (EGP)

Several users have reported that new settlers will come to their settlements and then stand near the edge or remain uncontrollable until they remove this mod.

Fusion City Rising

Can cause a conflict where scrapping certain workshop objects (including plots) will crash your game. This is not guaranteed to happen, but multiple users with the scrap crash issue have reported that disabling this mod resolved the problem.

Nakano Workbench

Can break your ability to control settlers.

Outcasts and Remenants

Can cause a conflict where scrapping certain workshop objects (including plots) will crash your game. This is not guaranteed to happen, but multiple users with the scrap crash issue have reported that disabling this mod resolved the problem.

Radrose

This can cause the plaques to float and refuse to update.

Resurrection

This can cause the foundation plots to not sink into the ground correctly.

Spring Cleaning

This can cause the foundation plots to not sink into the ground correctly.

Unlimited Building

There are plenty of alternatives to this to increase your build limit. This particular mod includes old versions of vanilla scripts (which is really bad). I've messaged the mod author about it, but have never heard back.

Unlimited Companion Framework

Can cause issues with companions being flagged as unemployed settlers preventing new settlers from joining your settlement.

Non-DLC Unofficial Fallout 4 Patch

This version of the unofficial patch is no longer supported by the creator. They now only maintain the version that requires you have all DLC installed.

Welcome to Goodneighbor

This mod has a number of problems. With Sim Settlements it can cause the Call Town Meeting function to get permanently stuck in a black screen. It can also cause your settlers to quit functioning.

Xbox Specific Issues

Place Anywhere

To use the View Plaque button, activate the Place Anywhere object in your inventory under Aid (you can craft this at the Chem Workbench under Utility, if you don't have it). This will bring up a menu, change the Options Menu to OFF.
