I hv came across this bug. Contracts are not awarding any Reputations i hv attatched screen shot to show you guys. where the system msg says i reached rank 5 and finished contracts. But actualy it didnt happen
You have rank 5 with your Faction, not your race! Contracts only apply reputation to your faction reputation. This way you can unlock faction based items way faster than ususal. The only way to get the race up is to win games.
