Unsure if this is a bug or user-error on my part, but occasionally when using the mod the window will close but not reopen. The usual way this happens is that I close it using the X button on the UI after building a network, but the mod logo remains blue in the toolbar. Toggling the button on/off fails to reopen the mod and the only way to restart it is to quit to desktop and start again.

Am I doing something wrong, or is this a bug other people have noticed?
