been awhile since i played and missed all patch notes, so does iron and copper ore nodes respawn now?

I HIGHLY doubt this will ever be a thing in vanilla Valheim... Once a resource has been mined out, which changes the landscape, that landscape should not be something that magically respawns.

If you need more metals, go find some new nodes, because the one(s) you mined aren't coming back over time.
