I am on the 'The Big Dig' > 'Dig to the Strongroom'. I had travelled a fair way through, blowing through several walls, and I reach a wall I need to click 'activate' on so Sonya the robot will do her thing. Only Mel is standing in the way and clicking activate won't do anything. It's like it froze, so I threw some grenades around and shot Mel a bunch of times trying to get him to move, didn't work so I saved the game, exited the game, reloaded the game and this time I capped Mel with 2 direct head shots and all of a sudden Sonya does her thing and blows the wall down.
After this I make it through, only now Mel is on attack mode constantly and Me, Bobbi & Vincent keep having to put him down cos he won't leave us alone, I can't talk to him either.
NOW I've reached another wall to blow down but clicking activate has NO effect. Mel is going crazy, I've tried everything but am stuck at this wall with crazy Mel.
Has anyone encountered this? Any ideas or suggestions?
