I'm currently encountering an unsolvable glitch that makes the "Rescue the Shadow Creatures" Location Challenge impossible. The idea is to stay behind ice rocks so that the shadow creature you can grab doesn't burn up in the flare as you bring it to the shadow creature you can't move.
The issue is that it's literally impossible to get anywhere near the second one. The giant ice rock housing the unmovable shadow creature only protects you from the flare if you're within 10 meters of it. Go any further away and you'll be affected by the flare, even if you're practically right in front of the giant ice rock.
There's no ice rocks anywhere in-between the closest ice rock and the target ice rock, therefore it's completely impossible to get anywhere even remotely close to it without the shadow creature burning up. It looks like the flare blocker is unloading itself waaaaaaaay sooner than it should.
