I was doing the third part of the mission Dawn of the Space Age. I was supposed to construct a rocket that could orbit Kerbin. The mission required me to make a 30t rocket (why??) and so I wound up making a really long rocket (which I've attached to this report). When I put it on the launch pad, it immediately bounced up, then when it landed back on the pad I got a mission failure. I never even got to turn on the engine.

I'm using the 64-bit Windows build of the game.

Note: I can't find an appropriate category to file this bug under. There's no "Missions" or "Making History" category.

I can confirm I also ran into this same issue. Any craft bouncing on the launch pad will do this in this mission. I am not sure about other missions though.

It might just be an issue with the new launch pad and not the mission or the ship. The first time I loaded your ship in the Sandbox, there was no problem at the KSP. I then ran the mission and when I got to the 3rd part like you mentioned, I imported your ship. The mission detail said it required 2 stages and it had that, but it wasn't recognized until I picked up one of the icons from in the staging area and put it back. Once the requirements were satisfied, I launched the mission and found it to sit steadily on the launch pad. The only difference is that I have the difficulty setting to make buildings indestructible, so I wouldn't have any more problems with the launch pad collapsing under a huge ship. So you might be having a difficulty with the stability of the launch pad as a destructable object.

I will say this however. Your ship will not get off the ground because the engines you have chosen are not strong enough.

Vessel placement at mission start has been improved to help avoid this.
