On my lvl 2 House, I occassionally get Limestones and Rein Wood. Do these spawn each reset, or when I log in or when?

Sometimes I have a few and other times 0 but cant see a pattern.

you get 2 limestone and 1 reinforced wood per restart provided, you go interact with the level 2 house, so unlock and check gear

Ahh that's how it works. Thanks for that. Annoying as my lvl 2 house is so difficult to get into due to its bug.
