A longtime 10,000 hours TW:WH player, I tried SFO for the first time this week! Tyrion Legendary campaign, adjusting many SFO settings to make it more challenging. I must say, it's one of the most fun campaigns I ever played -- managing things like Control, Replenishment Rate, and even Recruitment presented unique challenges and tough decisions. I was loving it. Then, at Turn 37, over the end turn, the game hiccuped and crashed while calculating AI turns. I turned all graphics to Low, loaded again, crashed again. I noticed it catches a hiccup and crashes on the 53rd faction's turn (I don't know which faction this is, due to Fog of War). Desperate, and resigned to my campaign being spoiled, I enabled the "Discover All" factions mod and Clear Fog of War mod, loaded and determined that AI Reikland is crashing my game on the Turn 37. I am closely examining Reikland and all their provinces and armies to see what unusual thing could be causing the crash. I can't determine what it is. I am incredibly disappointed and angry with SFO. Despite those 37 turns being very fun and challenging, the whole campaign has to be thrown away as there is no way to progress. I feel like I wasted an immense amount of time. I was using no other mods except for cosmetic ones -- Ultimate lighting etc. I disabled them all. They are not conflicting with SFO and not causing the crash. It is SFO all the way, and despite SFO being so popular among so many players, I will never be using it again because of this. What a disappointment.
