I attained diplomacy commendation tier 3 tonight by exclusively leveling with DOff dipXP assignments. I got the accolade for Envoy, tier 3 etc, but was not granted the power rewards, specifically, the transwarp to SB39 and the Diplomatic immunity power.
I do have access to first contact missions now, as well have the title envoy. I also have been granted the appropriate DOff token.
But no powers. In fact I have two Envoy accolades, and seem to have two Consul accolades as well.
I have reached Tier 1 some days ago and I got the diplomatic missions in the clusters from Sugihara, and also the title. However, I got two accolades for "Attaché" ... which is unusual. I wonder what will happen when I reach Tier 2 tomorrow or the day after, I'm quite close now with 13'100 of 15'000 points in Diplomacy and five high-end assignments for DXP until tomorrow evening.
