i was looking at the hangars in the shipyard in qo'nos and i noticed that an ''orion slaver''(or something) stole commodities and energy credits, is that your commodities and energy credits,or the enemies?
There is no theft ability in the game, from players or NPCs. Most likely it was just somebody doing an emote. There's an old troll trick dating back to Ultima Online to do /em stole 5 gold from you! and see who you could get angry at you.
