Comment 2 for bug 1781290

@Holger, unfortunately this is a side effect of changing our logic (and op-amp) symbols from having power pins on every unit to having a separate unit for just the power pins. Your best bet is to checkout the old logic and op-amp symbol libraries or create your own symbol libraries. If all goes as planned, the new symbol file format will allow for using separate power pin units and still generate a valid spice netlist. Sorry about the hassle. Changing the symbols resolved the hidden pins issues which most users didn't like but it created the problem you are experiencing.
