You might have already been alerted to it on your Discord server, but the Doppleganger is bugged. I can't even mouse over it in my inventory will instantly dying. I had to use a mod to open the inventory on death to even look at it. It had no modifier. I run with so many other mods, I don't know if there's an odd interaction happening. I checked the wiki and found this is only supposed to happen on reforging, since I noticed the Goblin Tinkerer died for seemingly no reason. I thought maybe the boss bag spawned it with a prefix, but it had none. Is this feature really worth it if it can bug like this? You're basically forced to deposit the item in a chest via Deposit All to get it out of your inventory without mousing over it.
