Just in case you are confused on why you're not getting double exotic components. Expertise Surge and Optimization Surge are 2 DIFFERENT events that affect different materials.
Optimization = Tactical Assessment, Gear Weaves, Weapon Alloys, SHD Calibration, Field Recon Data
Expertise = Receiver Components, Protective Fabric, Ceramics, Polycarbonate, Steel, Titanium, Carbon Fiber, Electronics, Printer Filaments, SHD Calibration, Field Recon Data, Exotic Components
Expertise Surge will potentially reward double prototype cores. However, we don't know yet
I repeat, you will NOT get double exotic components during this event.
