I got this error: WARNING: Matrix must be rectangular. Problem at row 1 in file isosurface.scad, line 2088 TRACE: called by '_mb_cuboid_basic' in file isosurface.scad, line 2148 TRACE: called by 'metaballs' in file isosurface.scad, line 2573 TRACE: assignment to "vnf" in file isosurface.scad, line 2573 TRACE: called by 'metaballs' in file gtest2.scad, line 37 Execution aborted which is somewhat puzzling because isosurface.scad is only 1779 lines long, so none of the offending lines exist. What's going on? This happened in both 2021.01 and in 2025.01.26.

If so, that's issue #4882 <https://github.com/openscad/openscad/issues/4882>. I worked for a while on a fix.  I think I ran into a testing stumbling block that distracted me - perhaps that errors aren't fatal (but warnings can be!).
