Mobs try to pathfind through corners, if there is an air block behind the corner. This seems to affect all mobs, including passive mobs such as villagers.
- Build a diagonal wall that mobs could theoretically walk around
- Behind that wall, build a pillar
- Climb on that pillar
- Switch to Survival mode
- Spawn a zombie on the other side of the wall
Sorry, I am creating this bug again because
MC-142516 was resolved as a duplicate of a non-related bug.
"Zombies, Creepers, Skeletons are all behaving like they have no AI for pathfinding at all. In bamboo forests or inside mineshafts they are unable to get around a corner (or double corner), just to reach me. Instead they are searching for the shortest direct path and get stuck."
All mobs are generally moving and are following me. They have also seen me, I usually hit them first and run just 5 blocks away. All the mobs in the picture have seen me, followed, but then stayed where you can see them. They just have no clue how to get around.
