Missing part when entering the game

[boaspessoal 8]

Hello,
I set up recently a system to bind special effects to a slot for armor and weapon. The issue appears when I relogin or warp to another map, while the body part seems to load in, the weapon has no effect. Everything works if I unequip and equip it back, it just doesn't seem to register the parts for the weapon effect when I load in. To be clear, the slot still has the item and is reading its value like bonus etc it's just the effect itself which is attached to the part the one that isnt working.
What might be causing this issue?

Thanks
