[BH] Toddlers/Infants despawn shortly after arriving on a daycare lot

Pack(s) required: For Rent / Business & Hobbies
Game version: 1.126.58.1030 (July 21, 2026 patch)
Platform: PC (Windows 11)

Description
When running a player-created daycare as a small business, NPC toddlers and infants arrive on the lot but despawn within a very short time — before any meaningful interaction can take place.

After checking my lastException.txt, I found the root cause appears to be errors in `small_business_situation.py` and `put_down_sim_interactions.py`. When an adult Sim finishes an interaction involving a carried infant or toddler, the game tries to calculate a valid placement surface to put them down on, but the target object returns `None`. This causes the situation to fail and the Sim to be reset and removed from the lot.

Errors found in lastException.txt:
- `AttributeError: 'NoneType' object has no attribute 'routing_surface'` — in `small_business_situation.py`, line 153
- `AttributeError: 'NoneType' object has no attribute 'transform'` — in `small_business_situation.py`, line 155
- `AttributeError: 'NoneType' object has no attribute 'get_carry_transition_constraint'` — in `put_down_sim_interactions.py`, line 333 / `put_down_interactions.py`, line 982

The last error also triggers a Sim reset with the following message from the engine itself:µ
"TODO: Exception thrown during Sim reset, possibly we should be kicking the Sim out of the game."

...which is exactly what seems to be happening — the infant/toddler NPC gets kicked from the lot.

Steps to reproduce
1. Create a small business lot configured as a daycare.
2. Open the business and wait for NPC families with toddlers or infants to arrive.
3. Observe that toddlers/infants disappear from the lot shortly after arrival.

- Mods active: UI Cheats Extension, a toilet trap fix mod — issue appears to be unrelated to mods based on the error traces.
- Expected behavior: Toddlers and infants should stay on the lot and be cared for like any other customer.
- Actual behavior: They despawn almost immediately after arriving.

    I had attached the file to my post and had an AI (Claude) analyze it to understand the content—it was actually the AI ​​that wrote the post. Sorry if it wasn't well-suited for the forum.

    I'll try it out on a save without mods but the bug appears gradually.
    I was able to play for several Sim days before it became unplayable (no toddlers would stay, but the parents do). . 

    (Sorry, I'm French; while I understand English well, writing it is another story...)

    You can't attach LEs unless you delete the first line. Please copy/paste the content or upload the file to google or onedrive and link.

    I'm setting this to review but it would be good if you post an unmodded LE.

    Okay, this one is even worse—the game completely crashed/froze, though the cause is more or less the same...
    I managed to play for 5 minutes—with a few toddlers sticking around (though I actually had more adults than children)—and then the game crashed.
    Sorry, I don't have the motivation to run any more tests; I just hope my reports help improve the game.
    Thanks again for your time! ;)
