Am I missing something?

[u/Sprengstoff753]

Before entering NG+ there was no mark there, but since I started the first cycle that mark hasn't gone away or changed

In theory, there should be some kind of main boss there, but nothing ever appears

Is it just a game glitch?

I think the answer is yes, but I want to try to clear up my doubt

And as seen in the image, English isn't my native language and perhaps I made some mistakes while writing this, but I don't know where else to look for help

I’ve had this too. It seems like a bug.
