      The bug

      Blocks that emit light which are placed or activate in lazy chunks (chunks were only redstone is processed) they will not cause a lighting update.

      How to reproduce

      1. Set the time to night
      2. Use the following command, replace [x] with: Minimum(8, renderDistance) * 16 (For example your render distance is 7: 8 * 16 = 128) 
        /setblock ~[x] ~ ~ sea_lantern
      3. Go to the position where the sea lantern was placed
        → It should emit no light

          Apparently this has been fixed somewhere between Snapshot 18w47b and 1.14 Pre-Release 3.

          Is this still an issue in the latest version?
