Unwanted cables/pipes

@Miller511 The auto-saves lag is known. Your left click is maintained active, while your mouse movements could be buffered and done all at once when auto-save ends.

That could be it, but the pipes that were planned were not on screen during the autosave. I all of a sudden got an overload message when heviwatt connected to a lower load circuit crazy far from where I was planning the mainline extension. My mouse was no where near that area during the autosave. Very strange.
