      Description

      The Bug:

      Vines can spread upward onto blocks that don't support it, if they have full collision on the bottom. For example, carpet, slabs, or sculk sensors. The vine will then break if given a block update.

      Steps to Reproduce:

      • Place down some slabs.
      • Place some vines nearby.
      • Increase the randomTickSpeed to speed up the process of vines spreading.
      /gamerule randomTickSpeed 1000

      →  Notice how eventually, vines will be able to spread on to the slabs.

      Information:

      Relates to MC-215365 & MC-191314. Reproducing this issue may be quite difficult as vines spreading onto the sculk sensor is quite rare. With this information in mind, it may take a while to reproduce.
