There's a discussion of this going around on the RotMG subreddit. (link here: https://old.reddi*****m/r/RotMG/comme...is_guys_vault/)
Do you guys think this is real?
Personally, I don't think it can happen but if the exploit is real, then it is extremely powerful. Imagine being able to access top player's vaults and taking out their UT items.
