it burns up in the battles that is why there is no Deut remaining to pick up. now you have to think of Gravity and where the Battle took place. if on the Planet yhen it could be pulled down and burn up on reentry you also need to think if it was on the moon then did the rubble fly off? it amounts to the same thing. this is a game we play, the guide lones are set up by what Admin thinks should happen. now you will say thet it costs Duet to build them well it costs Duet to run a fusion plant so there went the deut in the making of a ship. the cost of the deut is how much gets burned up Forming the ship.
In every online game i have played everyone has always wanted the "Deut" to more ready avaible in different ways. you ask why it is because it is the Hardest item to get in these types of games so everyone thinks of new ways to get the "Spice of life" so from me the anwser is no.
if you want more build your mines higher or dont raid for a few days to save what you earn from your planets, that way you will never run out of Deut.
