Now I've read the forums where BO skill points are not capped and we can train a BO with a particular skill which will replace the skill that BO has at that level. I also know that if there were any point awarded to that skill that was replaced those points are lost and the new skill starts at 0 again. But lets say I train a BO to Lt. Commander and then realize I no longer like the Ensign skill he/she has for space and want to train them on a different skill. Will that replacement of skill affect the points awarded at the other ranks? For instance will the Space category now be all 0's and have to be built up again or will it just replace the Ensign skill and make only that skill 0?
