I was exploring the Nightfall Bandit Dungeon and finding gold. When I looked at my earnings, I only had 473 gold total, which I assume was the total amount of my exploring.

Last time I checked (last night) I had around 3000 gold I believe? I haven't purchased anything or used it to heal my party or feed my sylestis, etc.
(I could be wrong about the amount I had previously, but I know I had more than 1000 gold and now I only have what I've found from exploring this past hour).

I logged out and back in but I still only have 473 gold. Help?

the only thing I can think of off the top of my head that would explain 'vanishing gold' is that, depending on how fast you were clicking/how much attention you were paying, you ran into one of the accursed healer fairies and accidentally told them 'yes, heal my pets' and didn't notice?

If you're looking to make gold, may I suggest the guide to making gold and more specifically the guide to mission pets and missions (missions are generally considered the one of the best ways to make decent gold, especially once you get all mission slots unlocked.)

Hello.

I can see that you had 2617 Gold as of 2022-03-02 at 00:00:13. It looks like since then, you've made some purchases at the Esior's Haven Market.

Oh, that must be my bad then.
I don't remember buying anything.
Thank you & apologies :)
