Steve, I think it could be useful as a separate function.
Perhaps, For performance reasons don't include it in the normal conversion process but have it as a separate button that Modders can click and "check integrity" before releasing a terrain.
I have to check but if you have missing target objects in between, the rest of the target area is not rendered.. (?)
Sometimes when doing manual editing of the target.ini w/ notepad, it's possible to make a typo/mistake/deletion and not notice it. (Especially after staring at this file for a whole night, getting cross eyed!)
And if this mistake is in an area you are done and tested already, you'll never notice it, until somebody else points it out..
