I am currently trying to farm Octavia for Helminth feeding and running Lua Crossfire Exterminate. I am noticing that the first cache does not seem to provide any reward (obviously a problem when farming Octavia).
When I open one cache in a mission, I do not get any resource labelled as "identified" in the end screen. When I open all three caches in a mission, I get two resources labelled as "identified" in the end screen.
