Ending bug?

[NitroRE3]

I have a problem here, I finished the game defeating doom and so on... but once the credits end I'm back in Doom's castle and there's nothing I can do or nowhere to go, actually I can go to Stark tower through the portal but I talk to      or Hank and they talk to me like I still haven't accomplished the mission, please help!

You did, that's just sorta how the game ends, you're free to explore the game world etc. if you want, you could start a new game with your previous heroes on a harder difficulty, but thats up to you xd
