I just purchased the GOTY edition (the full version, not the upgrade) and I am able to access every mission except Bangkok. I have uninstalled the game and reinstalled it, I have uninstalled just the Bangkok dlc and reinstalled it as well and nothing has worked.
If you are an Xbox gamer, make sure that Episode 4 is installed and then do a hard restart of your console (by holding the power button down for ten seconds), this is the method that I was told and it worked perfectly for me (and a few others that I’ve suggested it to)
thank you very much. that worked perfectly.
Welcome, glad to have helped Hope you’re enjoying the game
