Arena bug, and Duty exo upgrade

Hello there.

When I finish a kill in the arena, I go back to the camera of the introduction cutscene, then I am put back into the room and I can't leave.

Also, I have tried to get my Duty exo armor upgraded with nightvision from Petrenko, but he doesn't seem to give the upgrade when you take the option to try and do so. The only option I have left is the "Ah, sorry, not at the moment, thanks". Is there another upgrader?

arena is all messed up right now and I don't know when I will be able to work on it, sorry.

it may be that you don't have what he wants for it which will cause that option to appear

I actually found that I COULD peform the upgrade IF I bought (or perhaps have) a normal duty suit in my inventory with my exo-skeleton. Once I had it in my inventory, the dialogue options appeared.
