Strut connectors make parts of my spaceship decouple.

[Wok]

I wanted to test my ship to see if i could go on the mun with it. Everything went well until I hit space to decouple my first stage of reactors, the kickbacks. The Twin boar connected to my ship just decided to decouple even though there was no decoupler above it. After doing some adjustments, i realized that the struts connecting my kickbacks to my ship made the twin boar decouple. If someone knows what happened, it would be great to know.

 

Thank you!

Ohhhhhh, is that what's going on?  I've just recently started playing 1.3 myself, and I have this ship that keeps spontaneously disassembling itself during the boost phase, and could not figure out just what the dickens was happening.  Seemed like stuff was decoupling that wasn't supposed to decouple yet.  Now that I think about it... I think struts were probably involved.  The ugly part was that some launches seemed to work, others didn't-- it wasn't a 100% reproducible thing for me.

Sounds like it may be a bug (I've run into several in 1.3, just in the course of a day or two of playing).  May be a good idea to report it.  They're working full-tilt on 1.3.1, so right now is a great time to report bugs. 

Other than that, perhaps worth drawing the attention of everyone's favorite Squad-tester-who-hangs-out-in-the-forums, @bewing.  Any idea if this is a known issue?

Well, hmmm. Basically, the answer is no, it's not been reported yet, and I haven't seen it myself yet.

Sometimes newbies make ships that are distributed, shall we say, and are not in the form of a stack. And they tie it all together with struts, and then stage/decouple one piece, and then are surprised that all the struts vanish and the whole thing comes apart -- because the struts were the only thing holding it together in the first place, and staging breaks struts.

So I can see something like that happening here in Wok's case, perhaps. Maybe his twinboar was never properly attached to the stack above it. I need a craft file to be sure, but a picture would help.

In your case, though -- that's a newbie mistake that I know perfectly well you wouldn't make. So no. If staging away some radial struts breaks a stack, I need a craft file, ASAP. As you say, the next patch release is coming quick, and we need to get it on the bug list, fastest.

(And I need your other bugs, too!)

I'll see what I can do. It's a bit more of a "contraption" than my usual ships, and I was just assuming that the issue was something involving a self-collision with the ejected parts, which is why I didn't report anything.

Pinged you on this one because Wok's description sounded enough similar to what I was seeing to make me wonder whether it's a bug, especially given that I've already found and reported one bona-fide bug with the new struts in the vehicle editor, just yesterday.

I'll see if I can get a decent repro case when I can get in front of a KSP computer. Thanks!

FYI: There are two known issues with struts that have already been fixed. They manifest on the launchpad, though. Struts/fuel ducts clipped inside parts and struts/fuel ducts inside fairings will explode on physics load.

Yup, I already saw that one.  Here's the strut bug I found yesterday.

Anyway, I've been able to do some more testing on the concern raised here, and I've come to the conclusion that I think my own observations are a red herring.  Haven't been able to reproduce it consistently, and I have been able to observe some ejected-parts-collide-with-ship issues via F3.  So I'll pass on reporting that as a bug in my case.

Doesn't address @Wok's concerns, though, of course-- would love to see a screenshot and/or .craft file there.
