Drag & Place objects from a Sim's inventory does't work once you've left Live Mode— for example, after entering Build Mode, CAS, Travel, or Manage Worlds — and then return to Live Mode.
Basically, what happens is that when you try to drag an item out of a Sim’s inventory to place it, for example, on a counter, it won’t let you do it and the item stays in the inventory.
You also can't move objects that are already placed outside a Sim’s inventory. They simply revert to their original position when you try to drag and place them— for example, when you try to drag a cake from the counter to a table, it just reverts back to the counter once you try to drop it on the table. When you then try to move them in Build Mode they just disappear entirely!
It also doesn't work the other way round — you canNOT drag items into the inventory either.
After leaving Live Mode: I noticed this is issue occurs once you've entered Build Mode or do any interaction to leave the lot, such as traveling, going into CAS, or entering Manage Worlds. The only time the feature works is when you load your save directly from the Main Menu via the Resume option. However, once you leave Live Mode in any way, it stops working at all.
Can't Interact: Intercations related to an object being placed correctly also don't longer work— for example, you can’t add birthday candles or wedding toppers to a cake. The option is grayed out as if the cake isn’t centered on the counter, even though it is. The only workaround is to close the game, load the save via Resume on the Main Menu, and then add the candles or toppers without leaving Live Mode even once.
It’s not a CC or Mods issue, as this happens in existing saves and brand-new ones with no CC and Mods at all/ with them disabled.
