Trying this out again after a long hiatus from the mod, now the Eldar buildings are no longer invincible but the game will crash upon completion (destroying the final HQ). Necrons also has the fatal scar error, my work-around is simply just saving these two races for last and clearing the rest of the map first. Then I save the game before fighting either of the two races, complete it, game crashes then load back and fight the other. No completion screen, but at least I still played through both and feel satisfied (since there's no record saved anywhere of you completing the campaign anyway).
