Hello dear Tennos, I come here after searching for a fix to my inability to access Steel Path Duviri. I have done all the quests. (Including Duviri), I can in general access Steel path on the map, but not on Duviri The circuit. I have completed The Duviri Experience and I have completed The lone story once (the 6 missions and kill the boss) I also completed normal mode 10/10. Does anyone know how can I access Steel Path please? Thank you in advance, yours truly Yyoopi
