Just wanted to say I got a few random DCs during 2 or so hours and I'm amazed at how quickly the game recovered, it was barely noticeable (if only by the Poro's recall animations).

I did run into an issue after the first play session where it wouldn't record my progress towards the prologue checkpoints or it would get me back to the log in screen (the one with Ashe) if I tried to claim a reward. It fixed itself after restarting the game though

Edit: Someone else here ran into the same issue
