The crazy thing is, I never liked the visibly spinning props in IL-2 '46, anyway.
I don't know how IL-2 came to be married to Ubi. However it started, this relationship is no longer healthy and Ubi shows absolutely no evidence of wanting to fix it. Oleg, Luthier... I hope you can find a way to divorce IL-2 from Ubi and still keep the lights on.
