The bug
When you use bonemeal to a fungus (either crimson or warped) on few blocks below y=256 (eg. 253), they grow into huge fungus while tree saplings cannot grow in same condition, causing some of the weeping wines from huge crimson fungus to float in the air.
Steps to reproduce
Go to y=253 (or any height close to y=256)
Place a nylium
place a corresponding fungus on the nylium
Use bonemeal to it to make it grow
Observe how the weeping wines grow in the air
Use bonemeal to a normal sapling (eg. oak sapling) at the same height
The normal sapling won't grow into trees.
