I am having both of these problems as well. Project Red Transportation seems to be very bugged with the latest update. You can still use it, but you have to be very careful with what you do. I've found that (sometimes) you can avoid crashes with the Request pipe by submitting requests Very slowly and closing the window after requesting a couple of stacks. The crashes caused by the Stock Keeper chips in the interface pipe, as far as my testing has gone, makes the world unloadable unless you remove the chips, or the interface pipes entirely, with an external program. I should also add that the UI Background for the Request pipe does not load. As Zartach said, the window is no longer focused, and pressing E, for example, closes the window, H opens the Hats menu, and O toggles NEI on or off.
