Cura Problem solved

I have been going nuts for awhile unable to recreate quality prints that I was doing a couple of years ago. I was up to version 5.4.0. After banging my head against the wall for a couple of months I reinstalled Cura 4.2.1. and gone were all of the stupid routings that were leaving holes/detents in the outer surface. I am now back to where I was, printing good parts. I have not yet traced to the version where the change took place and may just stay with what works.
