Absolutely no problem with the game, before of after train, etc. And it is a gorgeous experience! I installed it using the offline backup game installers (setup_fallout_london_v1.01_iv2.31r3_(64bit)_(75422).exe and 9 other .bin files). No Fallout 4 from GoG but only Steam F4 goty, so then pure stand-alone installation without any external "pollution". Don't use the Gog installer, stay classic and safe with the 10 files...
