Could you please elaborate on that?
We still have no idea what you’re talking about.
Sorry for changing the content above don’t mind it again check the content above
We still don’t have any clue what the heck you are on about.
What is the issue? Should something be running which isn’t?
The picture of the error you posted says on line 117 that it couldn’t find the humanoid.
Line 117 is the Monster:IsAlive() function.
Which was called from line 359 at the top of the while true do loop.
The fix is to check if Humanoid exists as a child of Self, before attempting to check it’s HP.

I think I know what the problem is, you need to make it so the humanoid has a :waitforchild for it, so it would be
Self:WaitForChild(“Humanoid”).Health > 0 and Self.Torso ~= nil
Edit: torso is not part of humanoid so that’s what also could of caused the problem (unless there is a value inside it)

Sorry, the clues were hard to find
