I think Lacuna Pioneering questline is bugged

[Hikaru]

So after I completed the Suspecting Licht quest, the next quest didn't appear. But I accidentally managed to trigger an event related to him in Water Storage Facility. Sometime after that, another quest appears that tells me to go exactly where I encountered him, but when I go there again no event triggered. Hopefully this reaches the devs and get it fixed ASAP.

EDIT: accidentally trigger another of his event again in Ramus Radix Station, but the quest didn't update at all

I just finished the game, it turns out you can 100% the achievements without completely finishing this quest line as long as you can 100% the Pioneering Effort. And as it turns out this quest line broken on me right after we can get the needed furniture to 100% Lacuna pioneering effort.

Don't know if this will help. If the quest does not trigger try talk to ERHARD again. It works for me.
