Even if you do not complete the chapter, once the side goal completes when you have 20 Cerberus fur, the skyfall Cerberus stops dropping fur. I was lucky as I kept 1 as a pup and it is still dropping fur. Bug!
Thanks for the tip zoroak! I’ll be sure to keep my Cerberus as pups.
If I remember correctly from the last event like this, that issue resolved itself on day 3 or 4 (the next time you needed the drop) but it is still good to keep them as pups. It will prevent panic.

Remember that the adventures will give additional droppers from this event. I have already gotten an extra fountain, vase and Cerberus. That will be helpful later on.
