Hi Camille, I'm not sure if it is the same issue I encountered, but might be worth you to just briefly visit this issue: https://github.com/projectchrono/chrono/issues/290
In my case the Eigen::SparseLU solver was having issue, at the point that solutions themselves were off and it was due to misalignment issues. Not sure if it's the same, just FYI. Might be useful for us to know for which solver setup you are observing such issues!
