The bug
When light blocks are destroyed with an explosion, they drop sometimes. Since light blocks are supposed to act like air, this does not make sense.
How to reproduce
1. /fill ~-10 ~ ~-10 ~10 ~10 ~10 light_block 15 replace air
2. /summon tnt
→ ❌ Tons of light block items
Note
/setblock ~ ~ ~ air 0 destroy has the same issue
iPad Pro 12.9” Gen 1 on iPadOS 13.4 with Minecraft 1.14.30.
I tested this in the current release, 1.14.30, and it still exists. It has not been fixed.
A bug added in a full release can not be closed due to being fixed in a beta, only beta added bugs can be closed while in beta. Please see examples of other bugs here: MCPE-46217, MCPE-32355, MCPE-38101, MCPE-21856, MCPE-53033, and many more.
It’s probably an accident that it was closed instead of just a fixed version added. Hopefully though 1.16 will come out ASAP and we can get these bug fixes faster instead of having to wait many more months. I was so excited for 1.15 as being the largest bug fix update in Bedrock History, and sadly it’s been cancelled completely and delayed with a completely unknown date with estimates pointing to another 2-5 month wait. Now we are stuck waiting for 2 megamassive updates to release simultaneously instead of the far more important one releasing now when it’s so close to ready, and them getting the other later. Mojang release the 1.15 Bug Fix Update. Stop Delaying fixing the game!
