I received a "calabrese" error about 1 hour into the fight with witch queen and was redirected to home page. After I restarted the fight, I realized I had to start from phase 1 of the fight. This is so frustrating experience. The final fight is hard but worse part is that no checkpoint was created after certain phases of the fight to recover from this error. There are soft checkpoints to restart from death, but I was surprised that calabrese error even erased the progress in battle so far and caused me to lose over an hour of hard work. System info: https://pastebin.com/N6rjUvG5 Frequency of error: SO far only happened in final battle of witch queen campaign, but has previously happened outside of the campaign, in vanguard playlist.
