So I'm not exactly sure what exactly happened so I'll try to be as specific of the scenario as I can. When doing outside, spiral finished their battle and at the same time I died to an overtime. The instant my outside partner and I teleported for the next round, our screen turned green and we could not see anything else aside from our minimap. We were able to move blindly by using the minimap to be our guide. Entering a teleporter doesn't do anything about it but entering a battle seems to resolve the issue.
