Indeed, this is ridiculous, already bugged for such a long time it seems and still no real solution. I was actually surprised to come to this bugged quest since the game was really bug-free for me, until now. And arriving at this point at 36/38 Dry Steppes quest is special disappointing and really game breaking. I saw on YouTube someone doing this quest without problems even while there was an event running outside the cave, so that has nothing to do with it. I also noticed - apart from an already targetable barrier while bugged - the Elder is also marked with a white dot on the mini-map. I hope this 1fps solution works for me too, although it does not sound as a solution at all.
Edit: this 1fps solution did not work either (anymore). I just had to relog outside the cave until I got a not targetable barrier and then the quest worked fine and as intended.
I wouldn’t say it works 100% of the time, for me it was more of a “30% of the time it works all the time”, as i had to try a couple of times to get the timing right on when i would “tab back” to the game during the speech.
But yes, this workaround does indeed seem to work as i’ve now completed the quest on my character.
Hopefully they get around to making a more permanent fix to this issue as a “workaround” is not something everyone will bother with and some may drop the game itself for similar bugs in the game on other quests.
Does anyone has a workaround that works on xbox? Tried logging out and in, porting to town and resetting dungeons while changing world tier… nothing works
