Chrishna Posted February 26, 2023 Share Posted February 26, 2023 Ahoy support team, while trying to build a low profile lander with radially attached engines, I had some... 'interesting' behaviour of the craft, once it was put on the launchpad. The base of what I built was an MK1 Explorer lander to which I radially attached four ST-Micro1 Struts, followed by a TMP-XS hub. Inside VAB Whenever this combination of parts touches the launchpad, the TMP-XS immediately detaches, along with everything else that was radially attached to the lander can!? Outside VAB This was reproducable when starting the craft from scratch. KSP Version: 0.1.0.0.20892 Operating System: Windows 10 CPU: Ryzen 3950X GPU: RTX 2070 Super Expected Behavior: No disassembly on the launchpad or appropriate renaming of the TMP-XS Multipoint-Connector Link to comment Share on other sites More sharing options...
talon jasra Posted February 26, 2023 Share Posted February 26, 2023 Tested this some. Turns out every part node attached to those radially attached ST-Micro1 Struts fall causing all things to fall off. Also, those MicroStruts stay floating in the air.

LordKeene Posted February 26, 2023 Share Posted February 26, 2023 i built my ship. took it to a landing pad. falls into pieces. i put launch structures on it so it doesnt touch the pad, take it to launch pad, ship is intact but game thinks it died. take launch structures off and we are back to the ship falling apart for no reason.

Greyflex Posted February 26, 2023 Share Posted February 26, 2023 Had this issue, i tried to put clamps and move the whole ship upwards by a few meters, it kinda fixed it every time so maybe try that. Link to comment Share on other sites More sharing options...
talon jasra Posted February 26, 2023 Share Posted February 26, 2023 Are you by chance radially attaching parts to a ST-Micro-1 Truss? If so then that maybe the culprit. Link to comment Share on other sites More sharing options...

If so then that maybe the culprit. In my case, i had radially attached parts to the biggest radial decoupler, but i then removed them and my ship was still instantly falling apart.

If so then that maybe the culprit. Glad I found this specific thread. I think I do have the Micro truss in there, I'll check to see if that's a hold down point for anything. I'm more confused by the little dots. Here's what's going on with my vehicle: KSP Version - 0.1.0.0.20892 Operating System and version (Windows 10, Windows 11) - Windows 10 CPU and GPU models, any other system information which could be relevant CPU: i9-10885H GPU: NVIDIA GeForce RTX 2070 with Max-Q Design (laptop) Description of the bug. Expected Behavior - vroom vroom Observed Behavior - boom boom Steps to Replicate - load ship Fixes / Workarounds (if known..) - none at this time A list of ALL mods. If the list is long, please consider using a spoiler window. Other Notes / Screenshots / Log Files (if possible..) Link to comment Share on other sites More sharing options...

Chrishna Posted February 28, 2023 Author Share Posted February 28, 2023 (edited) I tested some more as well and to me it seems to be the hubs that trigger the problem, albeit in slightly different patterns. For example the girder version of the micro hub would stay attached to the micro strut, but everything else I attached to the hub would detach on the launchpad (again including all other parts radially attached to the lander can). I'm afraid we're scratching on the surface of something bigger here. I've seen videos of spontaneously detaching landing legs which seemed to enter the same zombie state as the solar panels in my lander can experiment (aka tumbling about in physics- and collision-denying circles).

JWag Posted February 28, 2023 Share Posted February 28, 2023 I had some weirdness with those ST-Micro1 Struts also when radially attached to a methalox tank. I think they detach mid-flight, causing this vehicle to explode. Link to comment Share on other sites More sharing options...

Bej Kerman Posted March 1, 2023 Share Posted March 1, 2023 +1 Happened because I wanted to dot the wings of my experimental VTOL with circular subsonic intakes rather than have the fugly radial subsonic intakes dangling fuggily off the fuselages and wings, and to do that I used these. Same result as you. Deleted and rebuilt every wing, took my craft apart to single out the perpetrator, point being this part is definitely the problem from the bit of research I did diagnosing my own craft. Maybe a tool was left on and that's what the dev-overlay looking dots are about. That's just speculation though, I just think those dots look too artificial to be a random artefact.
