I play on PS4. I went into the Tomb of the Pharaoh at some point and the cutscene for the boss triggered. However, after dying or quitting the game I found myself playing outside of the Tomb again. When I walk into the tomb now, I cannot get to the boss battle, because the bars are already raised.

I couldnt find anything about this issue, but read elsewhere, that you normally shouldnt be able to get out of the boss fight at all, before winning it.

Is this a known issue? If so, anything that can be done about it or is it a wasted save?
