While finishing my first game on incursion, it popped an achievement that said I mastered Reyna, but it didn’t give me her legendary at the end of the game. I looked in command and saw that her lore was done, yet the night before I had remembered I still had a lot of pistol kills to get. If anyone else had a similar problem please tell me if it was fixed.
Same problem here with ISIC completely finished his lore and no gear 
Yep. Same issue but with Alani after they reduced the requirements on killing Ambra. Never got the legendary gear.
No Isaac legendary for me either.
When i logged in, i just completed a mission (technically just went to a hardcore mission and died and got my Legendary, but my partner is mission his Gali legendary, but all my progression percentages are now off by 50% or so
