The easiest way is to teleport with the one you got. Though, be ready to press the pause button if it's a danger zone. Welcome to the forum <img src="/ubbthreads/images/graemlins/wave.gif" alt="" />
I'm always losing one also. So I goto the spot I left one normally Geoff and then teleport to the one I left behind and forgot to pickup.
God grant me the serenity to accept the things I cannot change, courage to change the things I can and the wisdom to hide the bodies of those I had to kill, because they pissed me off.
