I know it's listed in the major bugs that on order to get mob and resource nodes to respawns you have to reload client. But even that isn't working for me. Played all day at work and cleared out a 4 block section of mobs and resources. Been here 8 hours and reloaded client at least a dozen times. Same 4 blocks are still a dead zone. Has the issue gotten worse? Will it daily reset? Or only reset when they update the client now?
I too have been having this issue. It is unfortunately random for me. I could be at work, off site, or at home.
