Heads up for future reference this would probably go into technical talk, not 3D showcase.
After you reset the Maya tool make sure the scale is set to world, not component or object. Maya still scales even if its set to that but error notice will pop up. Worse case scenario, just increment save > close out > reopen. Should fix itself. That technique fixes a lot of Maya bugs.
