For some armors having to have 10 silver for the upgrading of armor and some weapons initial upgrading takes a painfully long time to accomplish. Please consider reducing the initial cost to make the process more bearable. Requiring a lot of a very rare spawn for an initial upgrade is neither fun nor makes a lot of sense. Is the goal here to make players want to quit from having to wait forever to upgrade one piece of gear?
None of them have anything to do with the problem of silver nodes, trees, chests, and mobs not respawing.
However as I said I’m done with this topic, and have actually stopped playing this game.
Plenty of games to play…
Yet you are here and complain 
I made a bug report about ore not respawning, especially the silver ore nodes.
