A World Has Leaked

[Schatzy]

Well, I fixed one of my previous problems and on both my computers I'm getting the message, "There are 4 worlds that appear to be persisting. A mod is likely caching the world incorrectly

[sEVERE] [ForgeModLoader] The world 18987de (world) has leaked.

[sEVERE] [ForgeModLoader] The world 54fed6 (world) has leaked."

Any help would be MUCH appreciated.

Update Dimensional Doors, or ignore these messages.
