@KiwiMrDee Thanks for your report. This is a known problem and has partially been fixed by the two above mentioned retraction fixes. The only known problem situation is where you first pause and then abort a print.
We will investigate this further, but I have limited time to look into the UM2 problems. The Cura 3.4 beta release is nearing, so perhaps we release the current list of improvements and move further improvements to a future release.
after aborting a print (UM2) the filament retracts meaning unless i manually progress it, the next print will start printing air until the filament reaches the hot end
