Ambious Posted February 25, 2023 Share Posted February 25, 2023 So I tried several different variations of this craft configuration and the same thing always happens: In all variations there are at least three stages. They all always attached with stack decouplers (or separators, same thing happens), and when I try to detach the 2nd and 3rd stage, it won't seperate - the two stages remain attached even though the engines fire and the fairings drop. First and second stage don't have an issue. I tried using structural trusses and moving the engines to another part and it still happened: And here's an example of how it looks post non-seperation: Here's a video demonstration: https://i.imgur.com/hUEeOrC.mp4 I did notice however that every once in a while 'jiggling' the craft will set the previous stage loose, but not always. I suspect it's a clipping issue. Anyone else experience this? Link to comment Share on other sites More sharing options...
Vl3d Posted February 25, 2023 Share Posted February 25, 2023 Yes, I've also experienced stages remaining attached to each other when decoupling. Link to comment Share on other sites More sharing options...

Klapaucius Posted February 25, 2023 Share Posted February 25, 2023 Yes, in fact, I even experienced it on one of the premade rockets that came with the game. Link to comment Share on other sites More sharing options...

When I swapped from the TD-37 to the XL decoupler, I had no issues getting separation...except for janky look. Link to comment Share on other sites More sharing options...

OC Geek Posted February 26, 2023 Share Posted February 26, 2023 Got all the way to Minmus and went to decouple my transfer stage, but no such luck. My lander engine came online, the decoupler thought it had decoupled, but the 2 stages were still attached no matter what i tried. Link to comment Share on other sites More sharing options...
flotey Posted February 26, 2023 Share Posted February 26, 2023 Not sure, but is your coupling and your engine in the same stage? I guess that's the bug. Every part needs to be in a separate stage. Link to comment Share on other sites More sharing options...
Sivako Aerospace Posted February 26, 2023 Share Posted February 26, 2023 I have encountered this bug as well. The best that I can figure from my testing is it has to do with the engine shroud. My best guess is the game is thinking the engine shroud is still attached even though it was staged and that is what is holding the stages together. The way I’ve been working around this is to disable the engine shroud and build a new one using a fairing. You can also time warp to phase the stages apart after you have staged.

dwing Posted February 26, 2023 Share Posted February 26, 2023 Known bug. Decoupling from some thrusters, e. g. doodle and labradoodle is not working. Also in some cases parachutes are not activated over the staging, Link to comment Share on other sites More sharing options...
fpb105 Posted February 26, 2023 Share Posted February 26, 2023 Try putting the decouple and engine start in different stages, I had a simialr problem and that fixed it. Link to comment Share on other sites More sharing options...

Stoup Posted February 28, 2023 Share Posted February 28, 2023 Also, if this does happen, and you manage to get to space, you can time warp and the parts should slowly drift apart Link to comment Share on other sites More sharing options...

When activated through the staging, the decoupler would only blow the fairing but not detach from the Poodle engine. Luckily I quicksaved moments before the Kraken struck and was able to experiment a bit. I managed to get around the issue by triggering the decoupler manually via the parts menu. This _must_ happen before the decoupler is triggered by the staging though. Otherwise it will just do nothing. Link to comment Share on other sites More sharing options...

Cytauri Posted February 28, 2023 Share Posted February 28, 2023 This bug has happened to me too. I have found a way to detach the spacecraft which is by time warping. After a few seconds of time warping, it decouples. Link to comment Share on other sites More sharing options...

Grimmas Posted March 1, 2023 Share Posted March 1, 2023 I have encountered this bug even when the decoupler was in a separate stage by itself. Once it happens, it happens reliably too. Link to comment Share on other sites More sharing options...

This also worked for me. I experienced this decoupling bug with my own craft as well as the pre-made "Kerbal-K2". Both crafts happen to use the poodle engine where the stack decoupler/separator fails to decouple. Link to comment Share on other sites More sharing options...
Scarecrow71 Posted March 2, 2023 Share Posted March 2, 2023 Not sure if this is the right thread to post this in, but sometimes staging simply doesn't work at all. Mashing the space bar does nothing, especially when it comes to deploying parachutes. Link to comment Share on other sites More sharing options...

Time warp may not play well with staging, even in atmosphere; once I set time to 1, I was able to stage my decoupler. (Yep, double checked and a new vessel refused to stage while time-warping in atmo flight.) Edited March 2, 2023 by Abe Kerman Link to comment Share on other sites More sharing options...

jclovis3 Posted March 8, 2023 Share Posted March 8, 2023 I have seen this with a variety of decouplers. In this video, you can see that even after staging, the control surfaces on the wings can still be actuated even though the only controllable part is on the rocket. This was my first attempt for the week 2 challenge before I switched to a series of connected aero decouplers. This is the link I sent in connection with report ticket 48476.
