I used Wrye Flash (www.nexusmods.com/fallout4/mods/3699), which alerted me to the missing Strings files. I then used the following utility to extract the Strings files from the main .BA2 files of the DLCs (DLC1Robot - Main.BA2 & DLCworkshop01 - Main.BA2): www.nexusmods.com/fallout4/mods/78 I've yet to verify if this is what's causing my game to CTD on fast travel in-game. The game loads up just fine for me when I select Continue from the main menu but my issue lies with a CTD on fast travel. Everything was working fine until Bethesda screwed everything up with the 1.5 update. Typical. Thank you for telling me about this tool
