Beam length reset with SML 3.9.1
Like in title, after updating the SML from 3.9.0 -> 3.9.1, I've noticed that the 40m all beams around my building were shrunk as if they were reset to basic length (just a few meters) across all saves, including before the update.
Rolling back to 3.9.0 made the problem go away in all the saves.
