Just started this. If I die during any trial, clicking on “return to checkpoint” gives me a network error and boots me from the game. So far, in the 3 times I have tried, this happened on the first time I attempted the first trial, and on my subsequent attempts twice on the third trial. It could be argued I need to just get better at playing the game, but it really is very annoying. I think I will avoid this storyline until it’s fixed.
It should be noted that in any other situation where I might click “return to checkpoint” i.e. fractals, I have no issue with this at all, and I am not given a network error.
