Kind of lightly browsed the community, but I am also confused on why Nova cannot be chosen on my survey as a main option? Apologies if I skimmed over the information. I am kind of disappointed, the opposum will not have the patchwork design like the concept designs which I assumed the patchwork would be at least what was most important to get accurate (I know sometimes you have to pivot if the manufacturer cannot get it to work - but I didn't see any explanation why they cannot?) Anyways, with the opossum not coming out like I thought, I wanted to select Nova on my survey, but cannot as they are not an option. I saw someone saying they are only available as an add on? But why?
