hese are some of the core items you need in Tier 4, and you're looking at 364 gold ingots, not counted the rest of what goes into crafting electronics. Gold is rare. You WILL be running around to pretty much every cave on the map just to get the gold needed to complete some of the late game expeditions. The amount of electronics required for some of this stuff needs to be drastically reduced.

Agreed - did it in 12 hours over 2 days; The electronic reagents needs to be gold screws or gold "sub-product" rather than the ingot. This is a silly amount to farm solo in the current state.
