Stack Overload On Downloaded Weapons

A few days ago, most of the weapons that I’ve downloaded started giving me a “stack overflow” lua error whenever I try to fire them. Any weapon that gets this error doesn’t do its firing animation or actually shoot (i.e. no damage to environment/npcs and no sounds play)

I have no idea what caused this, or how to fix this. Could someone please help me?

Bumping my thread, as it’s fowling up the whole game. It might help if I provide the exact line of text that comes up when I shoot:

“obi_weapon_extended.lua:20: stack overflow” (without the quotes, of course)

If anyone could explain to me how to fix this, I’d be extremely grateful.
