I was delaying this post because I dind’t want to post about something I’m not sure. And to be honest, I'm still not quite sure, I’m not a modder, I have no ideia about game coding and I’m still in my very beginning at creating CC. However during my CC tests, I noted one interesting thing.
It will be under the cut because the post ended up too long.
If you have Dream Home Decorator and have already played with cubes, you should know about disappearance issue. It’s very annoying and frustrating to put everything at the same place every time lot loads. I hate this too.
During my CC tests, I removed all my CC from other creators, I removed even all the scripts CC I’ve downloaded. I loaded the game with only my cubes. And most of the time, the cubes weren’t moved to family inventory at all. No cubes, no clutters were moved. Most of the time.
However things started to go wrong when I enable bb.moveobjects cheat.
I also noticed that when bb.moveobjects was disabled, some clutter slots were not available even when not in use. And when I enabled the cheat, these same slots became available again.
I can be very wrong, but it seems to me that the issue is somehow related to bb.moveobjects cheat and cluttler slots. Maybe the game removes everything it thinks is clipping, I don’t know. I’ve already seen this happen with a lot of stackable CC too.
How to avoid the disappearances?
I don't really think there is a way to completly avoid this issue without a game fix or a moding to fix it. It’s a game issue after all. However I did a few tests and maybe there is a way to decreased the disappearances at least. Sometimes you will have to replace them though.
Before place the cubes, disable bb.moveobjects. Then place them in the configuration you want. It can be a bit tricky if you try to snap half tile cube underneath one tile cube. I recommend you use two half tile cubes when it happens.
After place the cubes, you can enable bb.moveobjects. But don’t use their clutter slots, they are what make cubes desappear.
Instead of use cubes slots, you can use OMSP to clutter everything you want. Just make sure you use one OMPS for each clutter. (@pictureamoebae has a wonderful OMPS shelf, I high recommend. You can download it here).
Doing these three steps should decreased the issue occurrences, but some times you’ll still get them. Using the OMSP shelf is a good alternative because if by chance a cube be moved, you won’t need to place clutters again, just the cube. It will save some work and frustration.
I hope this long post helps you. I didn't intend to write so much, sorry x.x
