Those were not "maintenance resets". As far as I remember, there were two red flags in the 2020 event, both with around 30 minutes of resetting the grid. That was clearly a game glitch as the same thing had been happening in the pre-races. With enough time and enough people joining, disconnecting and driver swapping, the bug was eventually triggered. After that S397 did fix some online bugs and it seems the 2022 event went a bit better, but with a history of issues that were clearly game online code related, it's not surprising that many are pointing their fingers at rF2.
