Bug report:
Let's take for example a iHAL Probe Core (weight 0.5 t). Add a standart 2.5m Pebble Bed Reactor (weight 11.43t), total weight is 11.93t. Add a Thermal Power Generator (weight 6t), the total weight becomes 34.43t ( should be 17.93t) Moreover, instead of 2.5m reactor, let's add 3.75m reactor, total weight will become 32.883t. Add the same Thermal Power Generator (6t), the total weight will become 108.821t
