Nice attitude.....well i am lazy - and therefore can't be arsed to help.
When asking for help about stuff it might make it easier if you don't portray such a bad bloody attitude.

yeah hes right but.. i believe if you look in a previous post..

you can edit the Jersey field easy. IN freelancer data/solar/asteoirds

find the LI_jersey or sommit then open it using Biniq or another program.
Once there look for the [lootable section and put this in instead

[LootableZone
asteroid_loot_container = lootcrate_ast_loot_metal
asteroid_loot_commodity = commodity_scrap_metal
dynamic_loot_container = lootcrate_ast_loot_metal
dynamic_loot_commodity = WILD FIRE
asteroid_loot_count = 0, 0
dynamic_loot_count = 1, 1
asteroid_loot_difficulty = 50
dynamic_loot_difficulty = 1

this particular one is for getting guns.. just change the wild fire to niobium or something.. and dude why u wanna loot diamonds there i dont know.. surely you want to make em pop up outside the liepzig station and go out shoot beam dock sell? Easy when you a humpback..

please note that the WILD FIRE thing is wrong you have to find the ID number for it thne search it up in the wepaons folder and its nickname is what you want in the commodity secition
