I have 65 of these in my inventory and Crio has zero interest anymore. Are there any hidden crafting uses for this? It's still gatherable from seaweed.
No recipes are using this anymore and since Crio is not exchanging it anymore either, I think, it's just a junk item now. The only quest, which uses it is [Event] Terrmian Marine Environment Protection. But it's an event quest and you need only one item for it.
