So what happens to catalyst that are still in the sandboxes at the end of the event?

What happens to all of the stuff I have left over?

Do I keep that catalyst that I didn't use?

What happens to the catalyst bag I have in my inventory?

Do I keep my sun tokens or do they get turned into something else?

If you can answer any of these questions ping me!
:D

If it's like previously, so long as a pearl has been used on a sand box then once the fest closes they'll be automatically harvested when Krinadon gets around to it and the eggs will be put in your Hatchery, (and if it's NOT like previously then it's just literally 'everything that gets auto-harvested', not 'nothing gets harvested', so no worries there)

All leftover items that have been used from the inventory but not from the Summer Fest locations (Shop/Seeking/Sculpting) will become inaccessable

Leftover items in the inventory will, if used, join those inaccessible items.

Once next Summerfest rolls around, next year, all those items from this year that were not used, including Tokens, become Tarnished Sun Tokens (excluding things like Quick Dry Agent, which remains viable)

Tarnished Sun Tokens can be sold to the site for 500g per token.

I was really confused so thank you for answering my questions!
