I am still wondering why it was lowered by such a drastic amount. Not many people do the space missions, personally I like them, but to go from 12k to 1k barely makes it worth it imo. If you were to add the credit reward for all of the space missions I dont think they equal 12k which makes getting the grade 7 ship upgrades pointless if you cant make a decent amount of cash doing them, you would make just enough to cover the cost of purchasing the upgrades.
