Hello
I have problems with decouoplers after update to 1.3. I tryed clean install with only sstu mod and got same problem. Rocket just falling apart.
If i attach boosters to shuttle it falling. You can see it on a video. I have steam version of the KSP

I try to add strut connectors but in doesn't affect the situation.
Why it happening?
Update: I solved problem with rockets by adding reaction wheels module. But i still have problem with boosters
