Let's say it would surprise me, more likely solder reflow or esd.
Perhaps protect the chip more during the process, and be very quick. Use an ESD safe soldering station, and make sure that's working properly.
Look at the solder mask, and how much the board house shrunk that back, and what other things are in the proximity of the part changed, and that the capacitor part itself is not defective.

I have done this many many times and never developed an internal short to ground on a pin. I would look into your process and how the rework is being done.
