Without getting too specific, there is a script that performs an action in this area when it detects an item on the ground. That script requires most likely a 3 second delay because it does not always fire reliably. The server message is sent, which tells me the script actually fires but the actual main point of the script--the Action--doesn't always work.
This is a standard Bioware issue. Any script that performs this particular Action needs a DelayAction of three seconds or it just will not work all the time. Its not a lag issue, its an actual engine problem.
