  • Flew around

  • Left world

  • Re-entered world

  • Put Polished Granite, Lava Bucket and Slime Egg in Inventory

I just got this error when creating a new superflat world in 18w21a and opening the saved hotbars tab, which contains a hotbar I created probably in 18w14b or earlier.

One saved hotbar contained:

  • sandstone

  • redstone block

  • impulse command block (with no NBT?)

18w21a

Something went wrong upgrading!

How can this affect 18w21a, it literally says in the title that its 18w20c exlusive

Hm, let's think together about that fact:

  • At the time of creating the ticket, 18w20c was out.

  • Thus title consists of 18w20c

  • A few days later 18w21a came out

  • Bug still not fixed

  • Bug was affecting 18w21a

  • Title was not updated
