• Remove all your mods and test without them. Details here: PC, Mac
• Check the current Broken/Obsolete and Updated Sims 4 Mods thread in Game and Mod issues for known Mods/cc that crash the game or cause endless loading.
• Use the load button instead of resume and see if the save loads this way. If it does, test other lots than your regular family to see if they load.
• If none of the families load, create your own thread for troubleshooting in game issues.
• If it's a certain lot(s), see below.

Game crashes/endlessly loads reproducible when loading a certain household/lot

• Remove all your mods and test without them. Details here: PC, Mac
• Check the current Broken/Obsolete and Updated Sims 4 Mods thread in Game and Mod issues for known Mods/cc that crash the game.
• Move out the family and test if you can visit the lot or enter in build mode when it's just the lot. Also test your family on a different lot/save
• Sometimes the game throws lastExceptions while you trying to load. These give give an indication on what's broken. Provide them when creating a thread.
• If your game crashes when trying to load a certain unoccupied lot, especially in build mode and for buildings that worked before Patch 1.103.205/184. please use this thread: Endless Loading/Crashing when trying to load a certain lot
• If your game crashes because of a certain family, please provide them in the gallery and create your own thread for troubleshooting in game issues.

The map doesn't load and stays a white screen

• If it never worked and you are using T.O.O.L or other mods, make sure you have the newest version of those mods.
• If it worked and stopped working after you placed a lot in that particular world, please use this thread: White Screen when loading world (Patch 1.109.207)

The game goes back to the map when trying to load a household

This behavior has multiple causes. You can read more info about it here:  Loading a family just reloads the map. Most of the time you will get an error code but sometimes it just reloads the map. In most cases the game throws a LastException.

• Search both the Bug forum and Game/Mod issues if your error code already has a thread. The first two parts of the error code are relevant (For example 102:a0adad34). If there's a thread, check for solutions and if you need further help, post there.
• If you don't find a thread or you don't get an error code, create your own thread and post the LastException thrown (you can find the file in your documents folder. To upload create a rar file to upload or copy/paste the content in spoiler tags to your post).
