Resource Node Talk.

How do resource nodes work? How can you make them respawn and how long is the respawn timer?

you don’t make them respawn. they respawn automatically.

Since u seem new, u might wanna know that there is an ongoing bug regarding nodes type (woods and stone), if u jump on 1 of them, and start looting, u’ll be likely to recive a huge ammount of falling damage, sometimes enough to kill urself;
Returning on topich, as said above, resources respawn automatically, the timer should be arround 5 minutes (but the location is randomly selected, which make that statment only hypotetical).
