Confirmed, I have the same bug. Decoupler fairing will be jettisoned, engines fires but stages do not seperate-
Workaround: Either put engine and decoupler in seperate stages or decouple manually (via right click on decoupler)
Hmm...
Neither "patches" nor "ConstructionPorts.cfg" are present in the current version? Am I missing something? Or is this feature now included?
<edit>
Oh, I see, I am on 1.10 (bcz of RSS/RO).
