[S] 'Shovel Snow' interaction resets Sims

Please follow these steps to test  your game on a completely vanilla game with no mods/cc (without BE, MCCC as these are also mods)

• Move your mods folder to the desktop
  • Delete the following files from your user folder.
  •   localthumbcache
  •   Any lastException Files
  •   Any LastCrash files.
• Test a new save
• Afterwards, check your Documents folder and check for any new LastException files. Provide those either by uploading the file to a third party site or copy/past the entire content of the file to a post in this thread.

I retested the issue in a completely vanilla game with no mods or CC installed.

Steps taken:

• Removed entire Mods folder
• Deleted localthumbcache
• Deleted cache folders/files
• Started completely fresh save
• Used random EA-generated Sims
• Tested in snowy conditions

The "Shove Snow" interaction still fails consistently and resets both Sims during the animation transition.

The generated LastException confirms:
Modded: False

The error references:
AttributeError: 'object_terrain' object has no attribute 'slot'

Interaction:
social_snowEffects_ShoveSnow_Ground

Additional traceback references:

• jig_group.py
• _can_picked_object_be_jig
• Transition Sequence Failed

Other snow interactions still work normally (snowball fights, snow angels, snowpals).

Hopefully that link works, but here's a video I made showcasing the bug in a completely vanilla save.

The video shows:

- Sims successfully performing other snow interactions

- "Shove Snow" consistently failing/resetting

- the reset occurring during the animation transition phase

Same exception/problem for me. 

Since the latest patch, the "Shove Snow" social interaction consistently fails and resets both Sims during the animation transition.

The interaction begins normally:

Sim picks up snow

Sims move into position

Moodlets/social effects still apply

However, the shove animation itself never completes and both Sims reset/cancel the interaction.

Other snow interactions still work normally:

Snowball fights

Make Snow Angel

Build Snowpal

The issue occurs:

in existing saves

in completely fresh vanilla saves

with random EA Sims

in open areas with no objects nearby

with mods removed

I tested this in Mt. Komorebi on a fresh save with only MCCC, UI Cheats, and Better Exceptions installed, and the issue still occurred identically, even with random EA generated sims. 

LastException / Better Exceptions output references:

social_SnowEffects_ShoveSnow

Error:

AttributeError: 'object_terrain' object has no attribute 'slot'

Relevant traceback references:

socials/jig_group.py

_can_picked_object_be_jig

proxy.py:124

i have the same problem.
