Hi! The 1st issue is a known bug that slipped past our QA and Sony's QA to the final game (and unfortunately is going to stay since there's no more patches coming). 2nd the drops are random, but it shouldn't be very hard to get good loot especially if you do Ark Ship missions.
Your translation worked fine, hopefully you can understand my response as well. I don't know about the Spanish gaming communities
Maybe you should start your own!
