      Description

      The bug

      When two (or more) dungeons intersect each other it can happen that a chest generates at the location of a spawner. This causes the chest / spawner to become corrupted because the game places a mob spawner block with a chest block entity (can be verified using /data get).
      This causes the following error and warning to appear in the log:

      Failed to fetch mob spawner entity at (-1186, 17, -309)
      Block entity invalid: minecraft:chest @ fx{x=-1186, y=17, z=-309}
      

      Example seeds and coordinates

      Note: Due to world generation changes the following examples might not work anymore. In case no intersecting dungeons generate there anymore please do not claim that this issue is "fixed" if you cannot prove it.
