So I'm supposed to install the Palette Extender in the first step (because I don't have an option not to), then reinstall it again where it says to after the Item Revision to overwrite it... or...?Nope. Actually you won't be installing the Palate Extended in the first part(iow page 25), the PDF makes that clear (but you do so in the second part ... page 200).
There's the problem I was mentioning. I'm not supposed to install it in the first part, but when that component came up, I didn't get an option to not install -- just between compatibility install and full install. I'm hoping I either missed something in my last attempt (accidentally chose a prior option I shouldn't have without realizing it or something) or the fixpack or trimpack fixes this issue. If not, we're looking at an issue that needs to be addressed to improve (Mega) Mod compatibility.
