Does tiagos elite offers reset themselves?

As the title says im wondering if he resets automatically at some point since there is no timer for his elite offers or can they only be reset by buying the reset option in his shop?

They're not supposed to reset. There was a bug that made is offerings refresh (with the same items), and it may still be there.

The reset option in his shop is supposed to be the only way to change his offerings.

Experienced a reset of Tiago a few times. Completely random it seemed. Most likely it shouldn't reset at all, and when it does it's probably a bug.

To me first time it happened was after reroll, with after reroll i didn't have the pods tot buy the item I wanted. When I was back the other Day IT had been reset to the items he had for sale the very first time.

Since then In only reroll if In have enough pods tot buy a few things afterwards..

I don't think they should reset themselves. However, from personal experience I've seen them reset (or reroll, whatever the mechanic is). I wrote down two items I needed for my builds, did some expeditions in multiplayer for the resources and when I wanted to buy them, they weren't there anymore. No clue if it's a bug or working as intended, now I just farm some drop pod resources, reroll and buy if something pops up.
