Moisture should not be an issue with ceramics, but mechanical or thermal stress definitely is. Has there been rework on this capacitors? So check for handling /temperature of your soldering irons (better:use hot air). Check oven temperature/profile

Could be that your temperature ramp up rate is too fast. This could cause the flux in the solder paste to burn off too rapidly. When that happens, it can expand as it heats up and burns off, causing the solder to get spread out from the pad.
