  1. The 100,000 Stitch Wall: E4.2 starts sweating when a single object exceeds roughly 100,000 stitches. Ask for "Extra quality" on a 150k fill, and the math exceeds the buffer.
  2. The Corrupt TrueType Handoff: Did you import a vector from Illustrator? If the path has 10,000 nodes (invisible anchor points), Wilcom chokes trying to convert "extra quality" splines into simple stitches.
  3. The Parallel Processing Glitch: Ironically, modern multi-core CPUs confuse older E4.2 builds. The error often appears when one core is calculating stitch compensation while another is rendering the simulation—they trip over each other.
