This is the most excellent mod that exists.
The only 'bug' I'm seeing is that sometimes it does not stage and sometimes it does not accelerate time. If you manually stage it carries on as normal, but this isn't optimal. If you manually accelerate time it speeds away as normal. But again not optimal.
Specifically this is happening when I use the ascent guidance on a pretty stock rocket and sometime it doesn't accelerate time when using maneuver planner.
I'm using the dev build, I thought it may be better than he release build, but seems to behave the same way.
