Any ideas? Just started happening. When loading the world, it complains about a load of Twilight Forest block and item IDs being missing, and when it loads all my TF loot is gone.

Problem went away after a couple of re-starts. Weird.

Tried to find a cause/solution. Came up with: absolutely nothing
