["Came in a little hot!" error [Craft exploded when it hit 70,000m]]

Reported Version: v0.1.3 (latest) | Mods: none | Can replicate without mods? Yes

I was launching a rocket for a mission to the Mun or Minmus (I hadn't decided on the final location yet) and the moment I went over the boundary from Kerbin's atmosphere into space, it exploded.

Mission Time: 3:31:18
Highest Altitude: 69,974m
Highest Speed Over Land: 0 m/s
Highest Speed Overall: 855 m/s
Ground Distance Covered: 6m
Total Distance Travelled: 41km
Highest G-Force Experienced: 3.2G

Apoapsis: ~100,000m
Periapsis: ~10,000m

I was using the second stage engine to gently push my apoapsis up to 100km before I hit space. Once I got close to that goal I throttled down to 0 and waited until the intersect point, after which I was going to set a manoeuvre node and circularise. As I came up to the Karman Line I didn't notice any significant issues or performance drops, it all just happened instantly.

I love the work you're all doing, and I understand that you're still in early access. If it were easy everyone would do it. Take your time and do it right. Thank you!

Would this be available for later versions of KSP? I'll go back to 1.7.3 if I gotta to enjoy this pack, but I was just wondering what version roadmap was like :)
