All those large rotating objects are useless, all they do is disappear when you pick them up, they don't even collide! The pickups aren't a easy way to place exploding barrels that you can shoot all over the map. You need to specify what happens when player picks up oooo lets say pickup id 123, like fall or teleport or what. One example is the boxes, trashcans, and keycards at UltraMegaServer.
Btw, there are heck of alot of pickup ids, posting ALL of then with pictures could be a pain, but I'll see if I can post only the ones you should be worried about.(or maybe not)
