Fixed. The Rain-Forest East of Henesys has invisible search spots for the black-shadow quest, and they had no dialogue at all, so clicking them did nothing. They now speak: the decoys say nothing suspicious, and spotting the real shadow while the quest is active points you back to Roca to report it. Live now.

UDPATE: Shadow works and points back to Roca to report it. But clicking on Roca does nothing even though quest log shows quest is completed.
