Z hop not working after update to 2.1.1

[Aurasphere-au]

I sliced a large print after update, which took me a long time to get right after using the z hop which solved head crashing because of the large nozzle size, creality nozzles not being wide enough and gouging lines along with a host of other issues
On the second time of failed print on new version, I ran the toolhead trace and noticed that it was not lifting the head so Imported to Bambu and set up the filament with the identical parameters and it lifts as expected.

Is there anything that has changed in relation to that?
Yes I read about "reduce infill retraction"...was hard to find until I realise there was a search...being under GCode whereas other retraction relation options are in filamen

EDIT: When "retract on layer change" is ticked, it stops working totally...is that a feature lol? I mean am I missing something here?
