So i know no staff will read this, but Krinadon said that the extra catalysts will disappear. Maybe they become aged cata's? like Demons laugh Luffox become Luffox (Aged) Catalyst. :D

the stuff that is not used cannot be held over till next year. the current stuff will become aged next year yes but you will need to gather it next year it wont be there when brewing opens again. It would be too taxing on the database to store all that info from year to year. can you imagine how many catas there would be of people that have been here 5+ years if catas never disappeared xD and what would happen to the catas that were from years where they were no longer available. It would be a nightmare all round yus

True that.
