hahah yeah i had the same thing happen to me on my third time playing and i was by myself so i had no clue what happened i thought u could only do it so many times or something. any clues on how to find it wen it moves?
ok here's how it goes. There are multiple Mystery Boxes in the entire map. If you get a teddy bear, the box explodes for a few rounds. So until that one comes back, you have to find out where it respawns. There are also many respawn locations in the map as well for the box. It is designed so people dont just sit there over and over to try to get a ray gun or flame thrower (or any other good gun).
it just moves there are maps in other posts about this, and it doesnt really exploded the teddy bear rises up and the box shakes and caves in on itself
