More than likely the packet has some sort of sync key, timestamp, etc. in it to allow the server to know if the same packet is being resent to prevent exploiting. That or the server has a action chain that you are going out of order on of some sort and its being blocked.

Or the packet isn't "i got xxx gold" (stupid) but "i wish to pick up the item at x,y,z"
If there is no item there the server ignores it.
Or if you sold an item : "sell item at slot #" but if it's already gone it can't be sold

Locate your position in memory while you are standing at the position you wish to know would be the easiest way. Or if you know the packet that handles your x/y/z, just decode it from that.
