Found out the hard way about treated lumber and galvanized nails

Built a deck last month for a client in Austin. Used treated pine like always. Grabbed a box of regular galvanized nails from my truck. Three weeks later the heads were already rusting. Looked it up and found out ACQ treated lumber eats standard galvanized fasteners. The copper in the new treatment does it. Now I only use hot-dipped galvanized or stainless. Anyone else run into this issue on a job?

Yeah that ACQ stuff eats regular galvanized for breakfast.
