Cataclysm-dda: Seg Fault Crash on Load

[Ichthysdekilt]

Describe the bug

While exploring around a building the game crashed with a seg fault error. Now it crashes immediately on load.

Steps To Reproduce

1. Load attached savegame
2. Observe the seg fault crash

or

1. Wander around until you get a seg fault (trigger unknown as I couldn't load the game back to check what might have been around) and see if you can load again after?

Expected behavior

The main character wins megabucks.

Seems to be a case of #41352, crashes while loading item locations for avatar's activity:

Hello! I got the same problem today:

17:08:08.427 ERROR : src/item_location.cpp:242 [bool item_location::impl::item_on_person::ensure_who_unpacked() const] Failed to find item_location owner with character_id 1
17:08:18.569 ERROR : src/item_location.cpp:100 [void item_location::impl::ensure_unpacked() const] item_location lost its target item during a save/load cycle

I found this post, but I dont know how to clear current activity. Any help would be very appreciated, thank you! Here's my save:
my_world_name.zip

@IYourDoomI Yeah, same thing. my_world_name-fixed.zip

A guide for anyone else who may stumble upon this:

1. Go to save folder and find a file with .sav extension (there _should_ be only one with that extension, but I'm not sure about that)
2. Make a backup copy of that file
3. Open the original file with a text editor (any should do) and find "activity" string (including quotes).
4. Replace "activity": { "type": "ACT_DROP", ... (may be something a bit different, e.g. "ACT_CONSUME") with "activity": { "type": "ACT_NULL", ...
5. Save the file and try to load.
