Well, I've sent a couple bug reports in game, if I remember well. Now I post it on the forums before i forget about it alltogether.
Even though I'm a Lt. Gen., the rewards in the Undine missions aren't Mk XI as they should be (and as are the rewards in all other missions). "Assimilation" and "The Return" offer only Mk IX items as rewards and "Fluid Dynamics" as well as "A Light in a Dark" offer Mk X items.
Good that the Assimilated Module has no Mark.
Well, apparently those missions haven't got rewards scaled to actual level. And never had, as far as I can tell (a couple months back).
