Pit progressing bug

I’m on my Barb progressing through a lvl 60 pit, I got through to the second part and eventually cleared out the who map, the portal to the final boss would not show itself. Does anyone else have this problem?

It means you skipped too many mobs on the first floor. You have to go back and kill them until you get the portal to the boss.

Thanks, I didn’t know I couldn’t skip the first part of the pit…
