I keep seeing a lot of duped posts, so I wanted to post this to maybe answer some of your questions and keep the thread count down. [Note, I won't get too detailed, I just want people to be aware of the issues before they make a pointless post].
1.
Bugged Coop Missions - These are bugged at random, sometimes you get a glitchy instance, sometimes you don't. They're aware and working on a fix.
2.
Bugged Data Recorders - They are also aware of these and working to fix them.
3.
Roller Skills Resetting - They are also aware of these and working to fix them, just try to avoid going over lvl20.
4.
Missing Weapons - They have a sticky up about this one, just submit a ticket and they'll give it back to you.
5.
Patcher Isn't Working - Aware and working on fixing it.
6.
Missing Pre-Order Items - They also have a sticky up about this, just make a ticket and they'll give them to you. (However, be aware you may not be missing them, you may just need to claim them from the Store in-game).
7.
Zero Damage in Arkfalls, Coops, etc. - Aware and fixing.
8.
Pursuits Are Resetting - There are many pursuits that reset, here is a link to a thread that lists and discusses them:

9.
I Bought A New Roller, But The Stats Changed Afterwards - This has been around since Day 1, they're working on fixing it.
There are many more that I just can't think of right off the top of my head, but just note that there is a patch coming out on the 15th that will fix most of the bugs.
