My subs are modified CUUSY and I have found all of the new items without issue (and like 7 meerkats since patch). Unfortunately the new pet doesn't have anywhere as much sale demand as the meerkat did and the meerkat drop rate is so high now that they are quickly dropping in price. Its going to take awhile for the price of Pure Titanium/Kamacite to go down to justify the cost of making modified sub frames now as there really isn't anything of value worth the investment since furniture sales have always been finicky.
