i can reproduce the problem. It is a bug within the solver. It does not correctly recognize an insolvable state of the assembly.
"Pleuellager-O.2" has two constraints (planeParallel and axialConstraint). Both constraints do a relation to an axis (one is the cylinder axis, the other is the plane axis). If you flip the last constraint, the axis alignment of both constraints get ridicoulus and the solver should signal this by an message "constraints inconsistant", but it does not. Instead of this, the part is adjusted to a wrong solution. I will implement an additional check next time.
I stumbled over a similar case last days.
P.S. Better delete the planeParallel constraint, but keep the axialConstraint and do a new planeCoincident constraint to align the faces. This should work.
