Re: OBJECTS ARE MISLABELED AND CAN NOT INTERACT

@benuathanasia  I've split your post into its own thread because the other thread was very old and would likely otherwise be locked.

Please move your sims to a different lot, just as a test.  Use "save as" to rename the save, so your original remains intact under its old name, quit, delete the five cache files in your user folder, reload, and see whether the problem is fixed.  For reference, these are the cache files:

• CASPartCache.package
• compositorCache.package
• scriptCache.package
• simCompositorCache.package
• socialCache.package

Please also test with a house on either flat ground or a standard foundation, as opposed to stilts or anything else.

If this doesn't help, let me know whether it happens in a new save.  I'd also like to know whether your computer runs Windows or macOS.

Things I tried before posting:

Playing a different lot with a different family (happens at the new lot too)

Clearing all the caches as described here

Uninstalling the game and reinstalling

No stilts used (didn't know that was a thing)

Windows 10

@benuathanasia  Did the new lot you tested also have a platform?  Platforms should work fine, as should foundations, but it's worth asking.

If this happens with items directly on the ground (or on floor tile on the ground), please switch from fullscreen to windowed mode, or vice versa, whichever you haven't been using.  Quit and restart in between.  And make sure you don't have any apps open that include overlays: Steam, Discord, etc.  If you play through the EA App, disable its overlay too, which is under Settings > Application.

If that doesn't help either, please test in a clean folder.  Move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, if it launches, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.)  Don't add anything to the new folder yet; just start a new save and see whether the problem is still present.
