Hi, Can anyone help me with my launcher? It's a 45 ton payload being launched by a lifter of suitable dV. The takeoff and ascent are smooth, easily controlled and uneventful until ap reaches ~73,000m and alt reaches ~ 55,000. At this point the rocket simply falls apart with no warning, no explosion, no flexing, it's just like the Kraken reaches in and snaps it in two. What's odd is that it's not breaking where you might expect, at the docking ports or at a decoupler but at the junction between the FL-R1 RCS tank and the Rockomax X200 as shown by this picture. I have autostrutted everything in an attempt to solve this and added actual struts between what i thought were the weaker parts and indeed the soft junctions don't spilt. Just the one between the two tanks. I have even put 4 struts between the two tanks and it still suddenly snaps. Though I have noticed on the last attempt that it goes into a very tiny but rapid vibration about a second prior to breaking. Does anyone have any suggestions? Edit: Curiouser - it happens when the AP reaches just over 73,000 meters each time, this last failure the alt was 69km but still failed at the point the AP reaches ~73,000
