When I went to the forest to do lost in translation, I also picked up the side quest that is at the same location ( the forest area, I have forgotten the name ). At that point and shortly after, I was unable to do "lost in translation" at all. After I went through the third portal, all markers for lost in translation just pointed to the entrance to the forest. (I finished the side quest.)
I restarted "lost in translation" but that did not fix it. I relogged, but that did not fix it.
