Eeschema: lost connections after lost library reference

[Piotr Gałka]

I was wondering if to report it as a bug as it is the effect of my manipulations against the KiCad logic.
See attached screenshot - many IC pins are not connected and reason is not that something is not in raster.
I have changed the name of library containing W5500. Then when opening the schematic I didn't agree to rescue it. I wont to have all elements from libraries (in future no elements will disappear from them).
The end effect was question mark in square. I clicked 'E' at it and changed the library reference to point to right symbol again. And effect you see.
I suppose that at the stage of question mark wire segments were connected to be one, and when symbol get back were not divided at its pins.

I'm not sure if it really needs be fixed.

Does a save, close and reopen Eeschema restore the connections? (remove unconnected circle markers).

[Piotr Gałka (piotrgalka)]

After saving and reopening (not only schematic but the whole KiCad) the connections are not restored.

1). When I pointed the wire between pins 8 and 11 and pressed DEL the whole wire from L10 to pin 15 was deleted.
Then I added that wire (from L10 to pin 15) and it was connected to all pins.
When now I do like in 1). only a short wire between pins 8 and 11 is deleted.

Then I took W5500 by 'M' key and moved it a little up and down back at its original position.
What happened is surprise - the GND wire disappeared except connection between pins 29 and 23 and pins 19 and 48 (no wire from pin 23 til 19).
