You, sir, are my hero right now. I've tried my hand at reviewing that list before, and I wasn't much good at it. Is there any kind of trick to that work, or just switching between the games and a good eye? If there is a trick, I may well be able to help out (though I'm moving right now and bound to have little free time).
Also, you may want to pull out the conversion lists from the old save converter (

I'm pretty sure I destroyed the backwards compatibility with IN while I was at it (and possibly merged everything incorrectly, which could be what you see in the British Isles). The big thing is, if you can find map particulars that differ between IN and HttT, then we can put back in backwards compatibility if we want.
