Lt-05 Landing Struts cause rocket to pull North.

[Barang]

I'm getting weird behaviour using LT-05 Landing Struts in a science game. I've put up a series of images, but in summary adding any amount of LT-05s anywhere on my ship causes the rocket to pull northwards.

I've uploaded the craft file here.

Happens on both x86 and x64 versions, brand new install of the latest version and fresh saves.

Running on a squeaky clean install of W10 with an i7-2600k and GTX580.

Is it that they pull North, or that they go uphill?

Fortunately, it looks like we have gotten to the bottom of legs and wheels that migrate uphill when parked. There isn't much that can be done to mitigate the problem in 1.1.3, but the fixes will be included in 1.2.

@Barang, use strut connectors between the boosters or their nosecones and the central tank.
Or, rotate your rocket 90°, because the asymmetry happens to be just about right to make a nice curve into orbit.

The Kerbals who construct our ships operate under an arcane set of regulations, requiring them to add stiffening to some of the joints, but only when particular parts are present in the craft... or something equally mysterious.  In any case, the decoupler on your north-facing booster flexes more than the others, so the direction of the net thrust is a bit off-axis.

@Claw he did mean rockets pulling to the north, in-flight, where the pulling was triggered by the mere presence of landing legs.  The effect is more pronounced with just two boosters, and might be a nice test-case for any recent changes in auto-strutting.
