The circles cover the entire map currently, but they don't all appear at the same time. So you stand in the last circle to spawn (which coincidentally seems to be the one next to the entrance which used to be safe) and right before it hits you move to one of the circles that spawned before it (because the explosion will have already happened in that area) in a spot that's not being overlapped by a soon to occur explosion. Then you just repeat; right before that one occurs you move to another spot that was already blown up, etc.
It takes a little bit of timing and attention but it's doable.
Yeah I had noticed that but the timing seems really tight. So far, I've not been able to avoid getting hit at least once per AoE but I guess I'll just keep practicing. Doesn't change the fact, that the shields not working is a bug but I guess it's something.
Edit: Ok, I think I've found a safe-spot near the boss on the left from where u enter the bossfight. Really small though so Kurisu should be lured far away before pushing his HP far enough for the AoE to happen.
