I know that. But I also know that you tweaked something in HM12 for "creating a larger working area," and it's a little different from the original template. I don't know what else you did there.
That was a reaction to many complaints that "most of the map is covered in rocks, and there's nowhere to run around."

In my personal opinion, 6lm10a is the most interesting XL+U template, but that's for VT games; I don't know how it is in SoD, as I've only played it there once.
