What I did:

Connect fluid injector pipes to some industrialcraft machines, such as solar distillers. Then reload the game.

What happened:

Sometimes when reloading the world, the pipes won't be connected to the machines anymore. They can still be reconnected manually.

What should have happened:

The pipes should always be connected as they originally were before leaving the game.
