Finally some positive news on this one!
Summary:
- They will again temporarily disable all 2020 sceneries from streaming (but leave aircraft available).
- In 2 weeks time there will be a patch which lets users enable or disable content individually by themselves.
- Also in the patch they will reimplement safe mode startup so that if you get some bad content that breaks the game loading you can still get in to disable it.
I think it’s pretty clear these options should have been in place before the game was ever released, and it all shows how much of a rush job it was. But at least there’s now light at the end of the tunnel, at least on this problem we should be in a good place soon.
