When moving a light emitting block with a piston, it causes a light bug
as seen in the video attached to this report. These blocks stops emitting
light when in movement.
In case there is issues viewing the video
i will include this YouTube link:
+https://www.youtube.com/watch?v=J9aEIteSOmk+The image in this post shows the block in the movement.
The affected blocks are:
- Redstone Lamp
- Sea Lantern
- Glowstone
- End Rod
- Redstone Ore (when "activated")
This bug is prominent in version 1.13.2 but it's much worse looking due to the
old way of rendering lighting. I believe this bug can be resolved with the new
improved engine.
Thanks for taking your time to review this report!

[Mod] tryashtar Thanks for the clarification. I know in coding, many times an array starts on 0 and counts up. However i think that the number of blocks you enter should be the number of blocks spawned from the location you input. Therefore it should count 1 block, 2 blocks, 3 blocks etc. instead of starting from 0.
[Mod] tryashtar Okay it makes sense now. Sorry for wasting your time! Thanks again, and if you want you can close/remove this post.
[Mod] tryashtar You too!
