I Don't know if this is a client bug or server bug.
Newly planted sprouts disappear within a very short time. I have in 3 sessions planted 50 trees each time, only to return next day to find every single one gone.
Since players were not able to plant trees that survived, I tried with lvl 5(Dev) to plant sprouts. They suffer the same fate, everything gone the next day.
There used to be a paint terrain on the black wand, but that seems to have gone missing? Couldn't paint trees that way.
