Sniff the drop packet.
Use the x,y coords from the drop packet to send a walk packet.
Use the (dropcounter?) value you can get from the sniffed drop packet to send a "get" packet.
Now you can pick up every item being droped on the map instantly.
Pretty easy to program, just do it yourself.
Edit : oh, i just realised you mean these stupid trees

Just sniff a packet and resend it over and over again.
