Well thanks, I haven't played lol for months, but the option still doesn't appear to me, there's only one mission that I haven't done, since the others I have done, even if they are still in progress, and it's the second collaboration with another game, which I don't remember the name right now, which confuses me more, since I thought I had everything done, I mean finishing the whole thing with the lizardmen, I even raised the friendship of both leaders and nothing, so I don't have the slightest idea of what requirement I'm missing.
Sadly I found absolutely nothing, I literally did everything I could, it's not that I hate the game, but it's an aspect that they should improve, show exactly what you're missing, the problem with that is that they would have to do it for each mission and it would be tedious, but I really think it would be necessary, even so, if you somehow find the error or the event to continue with that, I invite you to share the one you did so they don't have to go through what we went through lol
Good news, I found the problems, So it doesn't appear in the missions, But you need to give Ruben water, water that Roushk's wife gives you (I don't remember what the water or the wife is called lol) after that you will have to go to alden, who is in the training area in the same place, in Nortcrest, And you will have to complete his mission, which is to establish trade relations with bareshade (you just have to talk to 3 characters that in the same mission he tells you and then with Tienen, you should have no problems) and thus the option will finally be enabled)
