Some of the creatures available via spawn have been improved a bit. They are passive1, passive2, and passive3. If you already spawned something from one of these creatures, you will need to erase it and spawn again to benefit from this change. Or if you are a coder, then feel to copy the new code to any of your previously spawned passives.
Note: all 3 objects have the same code, just different attributes.
Details:
As before, if you force them to wield something, they will remember it and will try to wield it again if someone pushes it out of their hand.
Here's where it is different: If you push the weapon out of their cold dead fingers, they will no longer try to wield it again until they are somehow alive again (auto respawn or cpr).
Also, if you force them to guard someone, they will remember this similarly.
To get a creature spawned from passive* to forget their weapon or guarded creature, just get the weapon or creature and wait a little while and they will clear their memory of it. Then drop the weapon or creature.
