JWag Posted February 24, 2023 Share Posted February 24, 2023 (edited) Description This rocket seems to reliably disintegrate (at least the first stage) after a couple minutes of flight. Alas, this still seems to be a problem after the patch. It's because of one (or both) of these parts: ST-Micro-1 STJ-3125 Environment OS: Windows 11 (10.0.22621) 64bit CPU: 12th Gen Intel(R) Core(TM) i7-12700F (20) RAM: 32613 GPU: NVIDIA GeForce RTX 3060 (12142MB) KSP Version Info: 0.1.1.0.21572 Saves Save from C:\Users\jimw\AppData\LocalLow\Intercept Games : https://drive.google.com/file/d/1CqICElOt2SaueBv2UVYyYCOYd3C6eCY9/view?usp=sharing Ksp2.log: https://drive.google.com/file/d/1iVmVlKaFBqzgof8dj0plTTSTc77dtw1I/view?usp=sharing Reproduction Version Info: 0.1.1.0.21572 Load JJKSP2 save Select Albatross workspace, load Albatross vehicle Make sure all four TT-38k decouplers have fuel crossfeed enabled, this seems to not stick between saves sometimes? Launch First stage is ignition of Thuds and Mainsail Second stage is launch clamp release Fly I typically start a few degrees' gravity turn at ~100m/S velocity Sometimes I'll use Action Group 2 to stage off the Thuds once propellants are below 50%, but this doesn't seem to be necessary to reproduce. After several minutes, vehicle disintegrates Often the upper stage survives, though it goes into a mad accelerating spin Edited April 15, 2023 by JWag Updating for today's patch release Link to comment Share on other sites More sharing options...
JWag Posted February 24, 2023 Author Share Posted February 24, 2023 the first failure is here (line 2387): [LOG 10:32:58.317] [Debug] <color=green> JOINT BROKE: </color> Owner: adapter_3v_methalox_2v-3v (guid: 0cc77182-692d-4fab-88ad-212688c50fde), Connected to: decoupler_2v_inline (guid: 7ad8f5d8-69d6-40f6-bf1c-193cf880556f), Force: 0, Torque: 4681.886 Thinking maybe this part is just weak, I've added four struts around the "adapter_3v_methalox_2v-3v", between the large first-stage tank and the decoupler. Alas, it does not seem to help. Link to comment Share on other sites More sharing options...
Hitori Posted February 24, 2023 Share Posted February 24, 2023 Once i am 70km above the ocean, and try to accellerate into orbit, the ship disintegrate after the engine being turned on for less than a minute, we talking about one engine, one fuel tank and one command pod with parashute on top suddenly splitting every single part attached. KSP1 was more stable than this on launch with 40 parts whobbling around... Link to comment Share on other sites More sharing options...
JWag Posted February 25, 2023 Author Share Posted February 25, 2023 With some more tinkering, the problem seems to disappear when I remove the RCS quads and their cubic strut "outriggers". Whether it's the quads being buggy, or whether having them on the outriggers causes the problem, I don't know. I'm at least able to get to orbit without RUDs now.
