And the first post to that topic you linked is a staff saying they WILL LOOK INTO IT.
So if anything you just confirmed they did notice it, but again “no siren”
Did you look at the links there? All of them see the ‘result’, not identify the cause.
So the information given is it exists, not how it happened (also there’s possibility some of them is lag and people’s sprite don’t move on your screen but they’re actually at another location, often seen if you go for the gravity pad chest in Legwyn where you’d see people’s sprite run into wall then next thing they teleport over to the chest)
Also, the nature of hacks and bugs are different. Bugs is something within the game’s code, and can be found/fix by looking into it. Hacks generally come from outside the game so they can’t ‘fix’ it, at most ‘prevent’ the method hackers are using.
