Ok, so. I maxed out the chest rewards yesterday. And I noticed that some of the chests I hadn’t opened yet were still filled in properly. Nothing wrong with that, probably just how it works. But I decided to open one just to see what would happen. I wasn’t honestly expecting to get anything, but I wasn’t expecting it to actually OPEN, either!! Just like I was expecting, though, I didn’t actually get anything from it. It was sort of just something I could still do. I was thinking of reporting it as a bug, but as the title says, I’m not sure if it’s actually a bug or not.
I did find it kind of funny when I didn’t really have anything to do in game when I was bored, though. I just thought it might be worth mentioning, bug or not.
