Server Crash When Rotting to Null

[naqaden]

The config says we can rot items into nothing by leaving the "rotten id" blank. When such an item is loaded before it rots, it persists beyond its rotting time. When such an item is loaded after it rots, a server will crash.

[11:09:47] [Server thread/ERROR] [foodfunk]: An error occured while attempting to rot inventory:
