      The bug

      Zombie Pigmen and Wither Skeleton won't walk through fire or over magma blocks, even though they aren't hazardous to them.
      To reproduce just make the pigmen angry and put the player somewhere where the only way the pigmen could get them leads through fire or over magma blocks. They won't walk through and won't get the player.


      It appears under certain circumstances they do walk over these blocks, so make sure to avoid them when trying to reproduce the bug.

      • In general mobs apparently walk through fire and over magma blocks if this is the only available path.
      • Wither Skeletons walk over magma blocks if there is only one, however when two are placed next to each other, they won't walk over them.
