Stuck at the Mountains in the mine - Hidden Object puzzle

[Zanatar]

So in the game , when you go through the big gates to the mines and you go down into the tunnels. There's a HOP there. (Hidden Object Puzzle).

In this HOP, one of the objects to get is a "grapnel" and there is supposed to be a knife on the right side (on the side of mine cart), that you click on then cut the rope allowing you to get the Grapple.

But the knife is NOT there for me.

I am playing this on iOS. iPad Air 2.

Is there any way to reset the HOP? I can't get the last item, ie: The grapnel, therefore I can't finish this puzzle, which would give me the Dynamite.

I do not want to restart the game.. Suggestions?

Resolved the issue. So looks like the location of the knife is different on the mobile version then in all the youtube vid walkthrough's etc. It's not on the right by the minecart anymore. It's on the top left.. kind of in the ceiling.

All good, was able to proceed.
