Hi when attempting to set up a roster for Blood Angels I notice that when I am working with my assault squads that when i change one of their weapons to a melta-gun that it adds an additional model to the unit thus skewing the points value. The option says to replace a bolter to a meltagun for only 10 points but it adds an additional model to the unit with a melta gun as well and it wont let me reduce the other assault marines to 3 to make up for it. This shows an inaccuracy in my point values. Is there anything I can do to fix this or is this a bug?
