If you want to remove the weapon (entity) from your map, just backup the files from the Entity Directory (Weapons i guess) (FPE and X) to another location (outside GG) and remove the originals (DBO too!!).
Start GG, open your map, editor will find something missing.. that's okay, should be the relocated weapon/entity.
Save your map. And after a reload it should not mention anything missing.
Now you can copy/paste the backup to the original place in the gg directory.
You might (need to) do the same for the Gamecore\guns\flintrock directory
This is the way i would remove entities that are (obviously) on my map, yet i can't find and i want removed..
Try again for standalone.
