How to reset a temple, especially roads?

I'm having a problem and i don't think, i'm the only one.

I tried the league mechanic by simply curiously interacting with it. But as usual, GGG expects players to fully study a completely overcomplicated and clunky mechanic BEFORE starting the game. Anyone who had NOT fully read some third party documentations about that mechanic ends up like me, having an unusable temple layout.

Of course, GGG does not implement a simple RESET button, cause this would interfer with play time metrics. And play time metrics are way more important to this company than providing simple solutions and fun.

Anyway. I have road artifacts on my temple map that persistently stay, no matter how often i close the temple. I'm out of ideas how to address this. Is there any solution to fully get rid of those?

Thank you.
