I found the Glommer statue at the full moon (along with Glommer) and picked the flower. I then mined the statue, but only received the 3x marble and not the Old Bell blueprint. Only realised this after I killed Glommer and found I couldn't craft the bell. Poor little guy ):
This is after I hopped from a really new SW world to RoG as Wickerbottom, so I hadn't learned the recipe beforehand or anything.
...also does anyone know the prefab name of the blueprint? Looks like the bell_blueprint prefab doesn't exist in SW>RoG worlds, couldn't DebugSpawn one.
Hopped from brand new SW save to RoG as Wickerbottom, mined Glommer statue after picking the flower.
