The issue is that Glommer doesnt show up. I managed to get the Glommer's flower and appeared when I did it but then disappeared and didnt see it again.
I was playing in a dont starve RoG world compatible with Hamlet andduring the full moon i took the Glommer's flower so i started walking back to base with Glommer behind me. Suddenly Glommer disappeared si I left the flower in one of my chests but Glommer has not showed up yet and it has been like a year in the game world time. Also the flower shows like Glommer is still alive because its not perishing.
