"This thing they announced for last year, then pushed back to this year and released to coincide with a massively hyped TV show was a complete surprise to us." Is that really FO:London's stance? I mean, I feel for them that it sucks, but to call it a surprise feels straight up disingenuous.
How do you prepare for an update when Bethesda don't tell you what is changing? It says in the article they had literally no correspondence from Bethesda until the update dropped, so the only thing they could do was keep developing and hope not too much broke in the process.
That being said, from what I understand is that the script extender broke, so they're just waiting for an undefined time until that gets fixed for the latest update.
