2013-03-30 04:51:02 [SEVERE] [ForgeModLoader] Detected leaking worlds in memory. There are 2 worlds that appear to be persisting. A mod is likely caching the world incorrectly

2013-03-30 04:51:02 [SEVERE] [ForgeModLoader] The world 240d35d2 (Copy of Copy of New World) has leaked.

The game mode the bug occured in: (SSP/Survival Single Player, SMP/Survival Multi Player, CSP/Creative Single Player or CMP/Creative Multi Player): CSP

The warning occurred right after I used a rocket to launch from the overworld.

Maybe it's a different mod conflicting?

I created a new instance with just Galacticraft installed; the warning still appears even going from the Moon to the Overworld.

Nope it's a known Forge bug, they are looking for a way to fix it.

 

[GSValore]

Ok, at least it's known then.
