Pigman Hide

I killed the "pigman overlord" but inadvertently threw the second "pigman hide", except that I cannot finish the quest if I don't have it and the "pigman overlord does not reappear.
Someone can help me ?

 

The Pigman Overlord should reappear if you go back to the same area, albeit you will most likely have to wait a little bit (hence why it may seem like it just doesn't spawn again). If it takes an absurdly long time (i.e 3+ minutes) and it still hasn't spawned, you may need to swap worlds.

 

this is what I also thought, however, since last night I have been revolving around the position where it is supposed to reappear but nothing is happening .. I may not be patient enough. In any case, thank you for the quick response!
