Thanks, I'll look into that one never had issues assigning to the 
L-System AA array. Does it cause a crash? If so could you do a 
stack trace to see if it comes from D runtime or just me not 
initializing it?

About 2) No Vulkan will lead to a hard crash, when querying 
instance extensions due to no vulkan instance being available. It 
might be nicer to have a clean exit indeed.
