Imperium - after eliminating 4th of Abaddon's general the game crashes to desktop after the main map dialogues are complete. Stuck. Pretty disappointing since that is probably near the end of the campaign.
Necro - after completing the Sentinel Worlds area, there is no way to advance to the next area, no link between SW and next area. Stuck,
I will try to play the 3rd also, maybe this one will have more luck.
