It probably needs every chapter flagged as completed on the difficulty, my final boss chapter is 100% complete on all difficulties after loading up directly after my checkpoint where the last boss is dead, depending on what you edited the difficulties might stack.
There are 2 chapters without difficulty ratings, one of which is after the final boss and is approx. 20 seconds long, the other is after completing the dome.
Thank you very much for the answers, I'll do is start another game and end the problem
Nice job thanks alot
Anyone got a save completed on hard? Wondering If it will unlock for beating game on hard. If you do post it please :)
Or even your half why through it, want to see if the levels show completed on hard.
