Is there a fix or setting that has to be used to prevent the crash that happens in MP when the grappling hook is fired?

Well first off, if you use a grappling hook in a server that doesnt have the grappling hook, it will crash. and if they DO have the grappling hook (Like the elite sides mod made by delta_57_dash) it will not crash. Me and my friends used to use grappling only on cloud city with the snipers...... fun times

So It shouldn't crash

Snipers+grapple hook or snipers+jetpack never seemed like a very balanced idea to me. After all, it gives them a potentially uncounterable advantage.

In any case, I thought I remembered that it didn't work in MP. Apparently, if you and a friend were messing around with it in mp, I am just confusing yourself. I seriously doubt there is any way to get the AI to use it well though. I wouldn't be surprised if it was like the fatray in the AI's eyes....non existant.
