[ANSWERED] TWR of 118, acceleration of 8m/s^2, but no movement?

[blorgon]

Modlist first. I've never had this problem with this modlist before, not sure why it's happening now. I haven't added or removed anything in 50+ hours:

I've been trying to land Minmus. VAB readout gave me something like a TWR of 14 or 15 on Minmus, but now that I'm there, my TWR is even higher (down to about 30 near the surface during descent). On my first attempt at a descent, when I started to burn retrograde to slow down, I actually started accelerating. Then, after quickloading, and trying to separate from my transfer vehicle, the rocket wouldn't even budge, despite the 8.17m/s^2 acceleration.

Any ideas?

Here's a bunch of screens (Dunno how to make gifs or take video during play, so you'll just have to scroll through really fast to get the effect):

PS: that fuel tank at the bottom with the landing legs is empty.

Your engines are exhausting into those drills is my guess.

Quicksave, decouple the forward section, try the burn.  That'll tell you right quick.

>Start accelerating

Check navball position. You need to Control From the right probe core (in the same orientation of the engine). Otherwise it's well possible to have probe core facing retrograde but engine facing prograde, and thrust is pushing you prograde.

>wouldn't even budge

Thrust into drill is also my guess. Check F3. If you see XX damaged by thrust from YY or something like that, and XX and YY are on the same ship, then your ship is not going to get acceleration from this engine.

Keep going.
