      Description

      Detector rails are stuck powered after the chunk unloads.

      I have several designs where I use a detector rail to stop a hopper minecart in place while it is empty, then it gets sent on its way once full. These designs break if the chunk ever unloads.

      How to reproduce

      1. Create a superflat creative world.
      2. /setworldspawn 0 0 0
      1. /tp 199 ~ 200
      1. /setblock 200 ~ 200 minecraft:detector_rail
        /summon minecraft:hopper_minecart 200 ~1 200
      1. f3 and target the detector_rail, it will show you that the detector_rail is powered
      2. destroy theĀ  minecart
      3. the detector rail will switch to unpowered after a few ticks
      4. /summon minecraft:hopper_minecart 200 ~1 200
      1. /tp 0 ~ 0
        /tp 199 ~ 200
      1. destroy the minecart
      2. the detector rail will remain powered
