I'm using Static ini checker and found some double objects in my static.ini
Do I have to remove them
And if the answer is yes, how do I locate and remove the objects
If your maps are all working well, and you can fly and save missions, then I'd subscribe to the philosophy of leaving well enough alone. I don't really think that double entries of an object have much adverse effect. You may end up getting different numbers for the objects when you choose them in the FMB for mission making, but as long as your game starts and your maps work, it's probably better not to try and remove the objects from the static.ini. That could be a cause for grief, even if you know how to go about it.
