If by Yeti you mean "auto save needs to be set up so it doesn't bork out my session or maybe I should turn it off completely and learn to save manually" or "my system can't handle the crap I throw at it and I should consider updating my gear or learning how to work with what I've got"... then yes, Stuntpickle... I think you have a Yeti in your house... and that Yeti might just be you.
Now, not that you're interested in solving this, post your system specs and maybe the more tolerant folks will help you tweak your system enough that it can sustain Yeti attacks a little better.
Cubase is just as prone to "Yeti" attacks these days too if the message boards are to be believed. Whether it attracts more or less yetis than Sonar I cannot speak to because I don't own it but I DO know I have been suffering far less Yeti attacks since since the release of X3.
I can say all this confidently as the imaginary CEO and official guitar licker for Gibson Inc (that's right folks... I have licked every guitar that rolls of the line because it improves the tone and gives it that lovely Beepster scent... and that is totally not made up bullpizzle just to be a numbnuts on the Cake and Bake forums).
Sincerely yours,
King of the Yetis
