How to reproduce

Load this STL file for the Dragon Burner: Alternative_Voron_Mounts/Modified_Mounts/V1_V2/STLs/MGN12H/MGN12H_X_Carriage_Lite_Lugs.stl (see https://github.com/chirpy2605/voron/blob/1c552edef49fac5af05f5b09b533ab4d0699a1dd/general/Alternative_Voron_Mounts/Modified_Mounts/V1_V2/STLs/MGN12H/MGN12H_X_Carriage_Lite_Lugs.stl)

Use the Arachne wall generator and slice the file using either a BIQU B1 profile or a profile based on the Voron Trident profile with 0.2 mm layer height.

Actual results

On layer 88, there is a single overhang wall generated going out to over 4000 mm off the print area.

See screenshot below, with GCODE line highlighted. Notice the blue line (labeled as line type "overhang wall") going off the right edge of the build plate.

Expected results

There should be no overhang wall line here.
