i was working on a new machine for my youtube channel and it works once then the detection observer will not detect the flowing lava to turn off the dispenser after the first time. have to replace the lava ever time. observer shows that it has constant power, not able to update it to remove the power state. able to reproduce if on demand if requested.
in the beta they have it where the sand, gravel, etc. dont break when they land on a glass block or scaffolding. they still break on top slabs, stairs, stained color glass.
i had MCPE-180388 i added my world to this bug fix where i was testing to see if block 36 was added to bedrock.
