Hello @bigeppy thanks for getting in touch with us about this quest.
After moving the rock so your friends can pass over the lava, are you able to run ahead and initiate a fight with the guards at the entrance? Will the players then spawn closer to you if you run out of the cave?
If not, are you able to capture a video clip of this so we can report this to our QA team to take a look at?
PlayStation consoles should give you an option to record a clip using the share button on your controller, then your console will ask if you would like to upload this to YouTube or Twitter, where you can then share the URL link with us, for us to be able to view.
