Can't Get Creeper Skin

Hello, for some reason it thought it was a good idea to throw away a creeper mask for a quest. A day later I am trying to get the creeper skin and it won't appear. Ive tried /fixquests but it wont work. Can someone help me with this?

 

Travel back up the tunnel to the cutscene where you get blown up. You'll land on top of the tree again, where you can get another skin. Creeper Mask is an untradable item rather than a quest item, which is why /fixquests doesn't do anything.

 

It's not a quest item. You have to repeat what you did in creeper infiltration to get it. Namely, going up the path in the ravine and triggering the cutscene where the scared creeper explodes. The creeper skin will then drop on the tree where you land.

 

Thank you very much, now I can continue the quest
