Fallout: London is a truly impressive mod, according to PCG writer Joshua Wolens—that is when you're able to actually get it working and navigate all the performance issues and bugs.
Since the mod's release, players have reported a few game-ending crashes, including one fondly named the "train crash," which has plagued most players. Not only will boarding the train to navigate apocalyptic London likely lead to your game crashing, but it will also cause a strange bug that halves players' HP.
