iv tried re loading a few times and still nothing. Do you think i should re install the dlc?
First, go back to a save from before you entered that cave.
Then reinstall the DLC and enter the cave fresh.
If that doesnt work I do not know what will.
If you save in the same area as a bug, that bug normally wont go away, so thats why you should go back to a previous one to be safe.
