That would likely have been just MCCC or BE for the reporting features. I pulled that LE file from my newly generated Sims folder after the folder refresh so it should be clean of anything else. Though for good measure I've just done another folder refresh, created a new save, and triggered another exception:

This is just me unlinking two pieces of modular furniture. In my original one I also moved the objects about a bit to generate the "phantom objects" I mentioned.

Edit By Crinrict: Adjusted formatting for easier reading

Same here! I wondered and tried many times that even the game crashes

I just had the same thing happen. I think probably different modular furniture because my LE had different numbers but the same error. And it happened doing the same thing. I have a bunch of mods and I haven't tried it without them yet.

Exception in <function c_api_clear_parent_object at 0x00007FF44A8D6950>, args: (185510000657239517, Transform(Vector3(260.594971, 159.669037, 293.307220), Quaternion(0.000000, -0.993681, 0.000000, -0.112237)), 662322470767008976, {9310AC72CD39CD0,1,World}), kwargs: {} AttributeError("'NoneType' object has no attribute 'slot_types'") (AttributeError: 'NoneType' object has no attribute 'slot_types')

This happens to me on an unmodded game. I also had three unconnected pieces show as connected and could not be disconnected, only moved as a group. And if I try to disconnect them by moving them to the household inventory, all except the one I select to move the whole group to inventory vanish and even undoing won't bring it back. They still exist, because I can't place anything else where they were, but they're invisible. (I have parts 1-5, I select #3 to move 3-5 to inventory, 4 and 5 are gone.) And unlike the oven bug (https://answers.ea.com/t5/Bug-Reports/DHD-the-standard-gas-oven-by-blazin-ladles-LE/td-p/12996405) which this reminds me of, moving the visible part doesn't seem to make them visible again.

If they're on a wall, it only seems to happen to things of different sizes and/or things that are not placed regularly. So if I want to make a string of 2x1 drawers along the wall, it's fine, but as soon as I place one that isn't uniform in size or placement, it breaks things. Which is generally not how I use modular objects.

It does happen to modular floor items too, but it doesn't seem to matter if it's a row of the same thing. They're all affected.

My lastException is many repeats of 

 Edit: Happens to Book Nook things as well as DHD. Deleting the items does work as a workaround.

Edit # 2: Now happening even with rows of the same and/or same sized things uniformly placed. No idea why it wasn't before.
