Can't Finish A Hero's Origin

I thought the cave the skeleton was in had more hiding and I was fiddling with the button which let the skeleton leave. Once I left the cave I googled what was supposed to happen next. I went to the entrance where the iron bars were supposed to have disappeared but they have not and I can't pass through.

 

You need to follow the skeleton it will break the iron bars and let you in

 

Did you disconnect or use /class at some point during the discovery? That seems to cause this issue.
It should be fixed for the next update.

 

Nope I just stayed inside the cave for too long and then the skeleton dissapeared.
