I was doing a monolith, and out of nowhere, a big dark circle appeared on the ground around me, and all of my damage was set to 2^31, which I believe led to an overflow so I ended up doing 0 damage. I took a video of it, with me changing zones. Logging out and back in fixed it.
This is a known issue. Could you link your build?
I apologize, but how do I link my build?
