Basically after the mission with the training yard (BOS quest line) after defeating the last monster fast travel seems to stop working.
Walking back and forth from Sanctuary and the other end of the map gets a bit tidious.
Please fix this soon I love the game but I might have to stop playing for a bit
EDITED: Also to add onto this my 1D 4H 32mins give or take a few mins.. .. Got corrupted and I have to start over... Not happy bout that...
Look Bethesda you've made great games that I've sunk 100's of hours into and you've don't lots of great work so please make a console update soon. Unfortunately due to the conveniences I'm going to have to stop playing for a while.
