Bukkit

I am running Cauldron 1.1199.01.146 as of 8/8/2014 and have installed the latest version of the Protection Stones Plugin (1.9i) and WorldGuard5.9. I recognize this error might not be related to your plugin at all. So I have sent a ticket to the Cauldron team as well.

The problem I am having is this, when the server is restarted, protection regions created by PS are gone. A quick /region info confirms this. This is not true for all dimensions, only Dim0. Atleast Dim7 is not affected though it has occurred to me that perhaps this is only happening in loaded chunks. Once the block is removed and placed again, the protected region will appear again until the next server restart.

This has apparently been occurring the whole time but was only noticed roughly a day or two ago. I updated to the latest version of cauldron to see if that might fix the problem and it persisted just the same.

I am wondering if anyone has experienced similar problems with Protection Stones.

Also, this error log pops up on my console. Sorry, I know it's kind of a garbled mess.

I should have probably posted this a while ago too. This error pops up when placing a protection stone. In game, the protection region is created and remains until restart. I've kind of narrowed it down to being a potential problem with changing the world name. But I can't see where in any plugin configurations to fix this.

I actually figured this out on my own just recently. The problem occurred when I changed the world name and was actually related to WorldGuard, not ProtectionStones. There was an instance of the old world's name in one of the regions which was throwing a null pointer exception that was only present in Dim0. This explains why this error didn't occur in other dimensions.
