[Update 29.10.0: Corpus Proxima & The New Railjack]

I was excited to see this update coming up, but as good as new things could be, i'm quite disappointed.
First, i agree with many of the previous comments saying new RJ missions are like doing normal mission but with a "briefing phase" of less than a minute onboard the RJ.. nothing more. (i felt quite disappointed when i got into the mission and found out it was nothing else than the worst defense map ever made, it took several minutes to do 5 waves, since we got there equipped for "general use".
Second, new content is bugged as hell. RJ Defense extraction is bugged and makes you fail the mission, also going from 1 mission to another without going back to drydock, leaves you stuck in the loading phase without any chance to exit or abort apart from alt+f4 (or maybe i had this bug due to the "failed extraction i said before, don't know).
Third: not only there's a lot of bugs in the new content, but also normal stuffs bugged out. i've been twice in the ESO trying to exp a sentinel, and even if when i pressed esc i saw it was gaining affinity, it didn't show up by pressing tab. When i got back to the orbiter i noticed it was back to lvl 0.

I'm done for today, hope to see some fixes tomorrow because this only makes me upset.
