I came across this once a while ago, I put a realy tiny object on the map and couldn't for the life of me remember where it was. I knew what it was so I took it out of the game folder before I loaded the game and then loaded the game. This effectively deleted the entity so that I could put it in again with a fixed script.
You will have to take the DirectX, fpe, dbo and bin files out to accomplish this but it does work.

I've got something to say - It's better to burn out than fade away.
