Shooting Range Doesn't Show Another Target..

Okay, Basically, I enter the shooting range, choose any weapon, and it begins (1st try). I pass the first level, the second one does not appear, and my character freezes in the way it is. I can't aim, neither the target appears. The clock keeps ticking though, and after a short period of time, I am able to move, and exit the shooting range, without the target being appeared. In the second try, I enter, and it does not show the target. In the same way, character freezes, etc.

BUMP
been 5 days, will we get a solution to this issue?

Mike suspects this is related to another problem involving an infinite recursion loop (one function calls the other which then calls back to the first over and over again). Eventually it fills the memory to the max then causes a bunch of stuff to break.

He has not been able to deploy a fix for this yet to the server.

Fixed in 1.5.7.
