Losing current project

New to Easel, but started using it today to carve a quick dust boot. Everything works good with the cutting, etc., but the issue I’m having is this;

  1. 1st carve works great, need to change some sizes, etc.
  2. make changes to drawing
  3. Re home machine for new piece of stock
  4. homing sequence stops after first Z bump.
  5. back out of program, ALL changes are gone.

If I restart program or x carve, homing works fine.
