I recently aquired a Locust and decided since I have over 100mil cbills I'd make a super expensive locust for the new Solaris dlc missions. I put in a 160 engine and it required 4 more heat sinks. When I added it in, it shot my tonnage over from 19 (after putting in an xl engine, UL gyro endo ferro etc) to 23. Not only do the sinks require slots they are adding in the tonnage and I seem to remember that they should be free or am I mis remembering something? (oh in Roguetech mod for Battletech the sinks are free tonnage..is that what I'm remembering? mixing mods?)
