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.

Nakano Workbench - Can break your ability to control settlers.

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.

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.
