So to 'fix' this issue I chose to plant my last surviving ender-lilly on a block of grass thats inside my base set up for decoration to wait out the long growth time. It's not in range of any growth speederupper or even a chunk loader.not sure why it would've uprooted but the sprinkler probably killed the rest. Bone meal kills enderlillys and pretty sure the OB Sprinkler counts as a bonemeal effect. at least thats what i remember from my testing. it very well couldve changed
However once again as I walked by I ended up picking it up as an item, as it has once again uprooted. I'm at a loss.
