I'm getting the same behavior with v3.19 installed via CKAN (completely stock otherwise). It seems that mirror symmetry in the space plane hanger is broken with the latest update. This occurs on wings and RCS thrusters and the attachment point is in the right place but the part is not mirrored correctly. For some reason doesn't happen on antenna or batteries. Downgrading to v3.18 seems to sidestep the issue for now.
