Product: The Sims 4
Which language are you playing the game in? English
How often does the bug occur? Often (50% - 99%)
What expansions, game packs, and stuff packs do you have installed? All
Steps: How can we find the bug ourselves? Using the bb.moveobjects cheat, place multiple objects together in ways that cause them to intersect and also on or adjoining to wall(s) of a structure. Attempt to place a wall pattern on a wall (does not necessarily need to be in the same spot as the objects). Attempt to delete a wall of the structure (does not necessarily need to be in the same spot as the objects). Turn bb.moveobjects off and attempt the same tasks. The behavior can also be observed at times by adding/moving walls/rooms and by applying pool trim.
What happens when the bug occurs? As you hover over the wall with the tool you have selected, some of the objects will be highlighted in yellow and then removed when you complete the action. This is more likely to occur with bb.moveobjects turned on. However, sometimes the same or *different* objects will be removed with it turned off.
What do you expect to see? Objects should remain where placed regardless of whether bb.moveobjects is toggled on or off and when 1) wall patterns are applied or 2) walls/rooms *not intersecting the objects* are added/moved/deleted. If objects intersect or are placed on a given section of wall and *that section of wall* is deleted, it makes sense that the objects attached to it would be deleted as well.
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
Did this issue appear after a specific patch or change you made to your system? No
This issue and variants of it have been around since bb.moveobjects was introduced. It was originally reported in this thread and was also widely discussed on the forums in this thread. Over time, there have been some improvements, which I believe have helped with some but not all instances originally reported. What I have described in this thread is still very much an issue.
Here are some screen shots of the issue.
1. bb.moveobjects turned on - about to apply wall pattern - you can see the objects near the wall highlighted in yellow, which disappear once the wall pattern is applied.
2. With bb.moveobjects turned off, the objects are no longer highlighted in yellow to be deleted, but now, some of the windows are:
3. And here, if I were to delete a connected room, the objects will be removed:
