Gani not being shown

[Yen]

I have an NPC which shows a gani moving, something like a boomerang.
The script is fine. I'm using the exact same script with a different gani in three different places, but this one won't display the gani to anyone but the person using the NPC.

I can see the gani just fine. Nobody else can.
When somebody elses uses the NPC, they can see the gani but I can't.

The index of the gani is 15, so it should be shown globally; the similar scripts are the exact same and they work.

This is the gani:

I've also tried using a constant image, rather than the first parameter, but it still doesn't show to others.
