Why are blocks respawning in my Minecraft 1.3 SMP server?
I'm experimenting with a new server on my own machine and came across an odd problem. Regardless of where I spawn, there is a square area on the map within which, no matter what block I break, it regenerates instantaneously. It produces no material, it just comes right back.
Outside of that area, everything works just fine. If I had to guess, I'd say the area is approximately 50x50 blocks square with the center of the square at my initial spawn point.
Additionally, I'm connecting to a server running on my own machine.
Is this a known problem? I searched the official bug database but found no bug related to this. And if so, what can I do to fix it?
