Enlarging model fails to create tree supports or complete some

[Spikemeister 0]

Hello, I'm attempting to enlarge a figure in cura 4.8 to 300% making it 12" tall. Being new at this I failed to do a proper review in cura before printing and a support for the sleeve didn't complete before the sleeve started to print, obviously creating a mess and ending a 3 day print. So some AFTER the fact review I also noticed that cura failed to even put in some tree supports for areas that needed support. My question being is there some parameter I missed when "enlarging" models to accommodate supports. PS. the model also failed to create some supports at at 200%. Picture in cura of sleeve starting to appear before support is there and that is exactly what happened in the actual print.
