Peeve: While playing Linden Realms to have somebody following and remaining BEHIND you only to grab the crystal in FRONT of you just before you reach it. Also, to have somebody FLY by so fast it makes you seem to be standing still. They then clear out a region before you can reach the area.
I fill sorry for those who are so unskilled at picking up crystals that they feel that they must cheat. I can only hope that they do not act the same in their real lives.
