Good morning, a few minutes ago, this character's main sword is gone.
I have the feeling that this happened at the time the loadoutfit command was used.
could you help me?

check all pages of your inventory

What could have happened is the sword was dropped because your inventory was too full. -loadoutfit unequips then quickly reequips your gear. If it was dropped, it's likely gone forever.

Ah! I remember this bug. Its one of the most dreaded ones, especially when you're carrying a Masterly Keened Weapon.
Not sure if it is still the case these days, that was 7 years ago.
If you dropped an equipment after unequipping your weapon/shield, when the area resets, it will be considered gone.

Workaround:
1. Make room in your inventory
2. Pick up the item
3. Equip the item
4. Drop it again
5. Pick it up again

Should prevent it from disappearing when the area resets.

Note: If you have one of those invisible equipments (IE: Cloak, Club, Helmet), DO NOT DROP THEM! It will register as dropped but you won't find it, ever!

I see.
checked all the pages of the inventory and it's really gone.
there were several things in the inventory at the time, it may be happened this situation that was described above.

It is sad to loose such a good item this way.

any ways, thanks for reply
