[BUG] Demo Grappler line disappears

This bug never happened to me during the beta, but has happened to me several times during the demo already. Sometimes the line on the grappler will disappear, but the hook will remain visible and you will still be grappled in to the point where it hits, but often I won't notice because the line has disppeared.

I am not entirely certain, but this seems to happen when I disconnect and immediately switch to my disc a fraction of a second later (which I do often as a measure to prevent refiring immediately after disconnect). It's quite annoying, not only do I get stopped/slowed by the grappler not disconnecting, it also takes me a second or two to realize that I am still connected and have to switch back to grappler to disconnect.

I hope you guys are still logging bugs.

So I am fairly certain it happens when you immediately switch to another weapon (or at least the disc) while you are disconnecting. In order to disconnect, you must fire at a spot where the grappler will hit. If you fire to a target out of range, the grappler will go through the shooting animation, but you will see no projectile or line. I even made a couple videos showing the effects:

Logged, thanks. And thanks for the movies too.
