Description of Problem:

In the Technic Pack, when interacting with an Energy Condenser with items being removed via a wooden transport pipe, exiting the energy condenser GUI causes the Saving Chunks screen to come up and the game to crash. Reloading the launcher and after loading up the world, it will cause the Saving Chunks error again.

Use MCEdit to remove the pipe, and don't do that again. Wooden pipes don't like to try to pull items from an empty energy condenser.
