Hi,
As said in the topic, after completing the chapter 6 of the story the next chapter didn't unlock.
I remember my computer crashing once during a boss scene so that might have been the root problem of it but now I find myself stuck. I tried resetting to different levels and nothing happened.
I tried resetting the 6th chapter and I get the final dialogue displayed but then am redirected to the level 1/501. And still no chapter 7 unlocked.
So unless the 7th chapter needs something special to be unlocked, I have a problem.
Thanks in advance!
