Ive had no luck upgrading 2x now: It gets through maybe half, maybe 2/3 of downloading files and it stops.. I get an "unhandled exception during upgrade - data error: cyclic redundancy "
Edit: make that 4X now. Just restarted the ED loader.. and still no luck.. same error
I have to admit as a console pleb it feels like we got kicked the crusty bread roll and told to deal with it again.
Personally as I write this comment it's 11:30 am on Patch Tuesday, and the lack of feedback is as usual deafening (at least I feel this way!) So 11:30 am came and went and no update. I am only guessing mind but this makes me think we wont see a patch today. No word (as it was promised!) from Frontier at all. So here is hoping the Patch comes on Wednesday some time.
I know I am feeling bitter towards this game which I backed at Kickstarter four years ago. Finally a release has beaten me out of playing my favourite game. Server issues all the time preventing me from playing. Frontier admitted changing something with the servers and still put the patch out knowing it was bug ridden. And they have the effrontery to say "good progress has been made cleaning up the bugs!" What bugs? What and where is the change log details we can look at and get fed up when we don't see what we know needs fixing not fixed. That maybe the stars will be put back as they were and the Gal Map sorted out at long last but the terrible server outages will continue as it has since day 1 of the game only now it's much worse since 2.3 was not so ceremonially dumped on the player base. It should have been BETA tested for 2 or 3 more weeks. Not rushed out for the Easter Holidays.
Just get the patch rolled out and the patch notes so we can all find out what it is you are going to release to us all. We deserve better treatment than we currently get.
