How are seeds generated in rotwood?

[HondorDrache]

I have a feeling that perks in rotwood drop out in the same way as artifacts in the binding of isaac, in Isaac a certain artifact can very often drop out in one day, this seems to be the case in rotwood as well.
In the last demo of the game there were days when there were perks for bombs.
There were days when there were constantly perks on the portals, and days when there were none at all.
on the first day of the update demo, stores always had "No Contest" and "Deus Ex" was very often found
Yesterday almost every race was "Body of Light"
I'm going crazy? It's time for me to put on my tin foil hat.
