serious launch bug

[Pupu]

I get a very bad bug during launch phase. Hard to explain but i try:

The camera seems to "switch" to the command pod, and then i cant stage correctly anymore. for example:

my rocket has the command pod on the top. At start the camera is focussed on the middle of the rocket (like normal). Then somewhere during the launchphase the camera switches up and focus on the commandpod. At this point i have no control over the whole ship anymore.

This occurs sometimes even before i hit space once, and sometime after up to 30 seconds.

:-(

ps: got Kas mod, g15 hud plugin, and mechjeb ( installed it but somehow couldnt find it )

edit: it says structural failure even before start between rockomax tank and rcs tank.. before i even liftoff...i think thats it. ^^

edit: doenst what i put on that rockomax fuel tank. it always gets structural failure at this point :-(

You might want to redesign or uninstall mods and try it. If it still messes up, then It's not your mods and you can reinstall them. A redesign is probably less trouble.

Before you start, the rocket is placed on the launch pad exactly how it was built - and then gravity is applied to it. That's a lot of stress and it may tear some parts off if the construction is not sturdy enough.

To prevent your rocket disassembling, either add some struts to keep parts at their intended places, or change the rocket to withstand shocks better.

Yeah, Kashua's got it; that's not a bug, it's your ship collapsing on itself from its own mass. MOAR STRUTS is the usual answer; I'd also build it so that the engines are sticking slightly into the floor of the VAB. When the game loads it, it'll automatically adjust it to set the engines directly on the pad. Some TT-18-A Stability Enhancers (launch clamps) wouldn't hurt either.

I wager you're using the large RCS tank. Those things have given me headaches in the past. Try strut-stitching your RCS tank to whatever's above and below it; that sounds like the point of failure. Alternatively, take it out and replace it with three or four RCS cylinders (four's got the same amount of mono as the big tank).

Thx for all the help. I got struts everywhere and the top of my rocket isnt very heavy but it keeps collapsing. I `ll just rebuild it :-/

If rebuilding the ship doesn't help, upload the .craft file. I may be able to see what's wrong and provide some tips.

[Pupu]

It did help. New ship consists of smaller tanks and this works fine.

If you get the problem again, press f3 to bring up the flight log. If something has broken, effectively severing the 'brain' of your ship from the rest, resulting in a loss of control, it should be listed in the log.
