Johntodd: PRO-TIP:
If you have the blueprint and materials for the Calcishroom, you can just build them on that planet! Then collect them and you'll have your 16 you need for the weekend mission.
(minor glitch: If you have already collected a few, you;ll have to "build" them too. Just plop down 16 and you'll be fine.)
I have 16 leftover if anybody wants them.
dashiichi: There are blueprints for the Calcishroom and the other decorations? Where did I miss that? When I select one to place which I've previously picked up it
does show "can build (some big number)" but once the ones explicitly harvested are gone, then nothing.
Didn't completely miss it - this is base building product or decoration. There is a building blueprint but back when those first were added I think that you had to first find or obtain one in the wild before the blueprint became available. Same applies to all or most all of the curiosities found on the anomalous planets.
Related to curiosities - any idea what the newest curiosity is? There is a new one at the end of that page in the Catalog.
Never mind - figured this out and it is a new curiosity named void egg.
EDIT - cleaned up the response on the anomalous building decorations and found the answer on the new curiosity. Haven't found the curiosity yet but will go back to a couple of planets to look.
