Basically, I've obtained all 5 loot chests on Earth. The easy one in the first building, the one on the Wizard mission, the one in the cave, the one at the cliffs, and the one in the Sepkis Prime mission. However, my chest count on the main Earth screen (where you can select missions from) only shows 4/5 chests.
I also heard that you get a bonus when you obtain all 5 chests (I don't know if this is correct), but either way, there must be something wrong. Does anyone know a way for me to reset chest progress, or sort out this problem?
