I updated the first post to add a few more TibEd edits.
Anybody creating an Ix or an Emperor campaign would notice some problems with those Houses. As Ix, deploying a MCV the game crash, and as the Emperor the player can't build his own Imperial Palace.
Changing that it's very easy, but requires an external program (TibEd) plus have some experience with the tool. For that reason I decided to add those editions already done to make it easier for everyone.
There are a couple more, like making the tanks to no be able to crush foot units or including the only practice type of units (grenadier, Stealth Raider...); check the first post for more info.
