Piglins and zombified piglins have 2 right arms, legs and ears. Hoglins and zoglins have 2 right tusks. This was reported multiple times, but either wrongly marked as Works As Intended or wrongly marked as Fixed (devs specified to reopen the issue if it wasn't the case, but the issue wasn't reopened). The hoglin one was discovered just now.

Attached is a pack that fixes the issue in piglins, the one in hoglins can't be fixed with a resourcepack.
