Not exactly a bug I don’t think, but my Heathlings often won’t mine the block immediately above them, making mining in any sort of upward fashion, litterally impossible.
When using the mine a Tunnel option, or w.e its called, where it mines a 4x4x4 area, they clearly show they can mine that block above them.
But then when I’m trying to do specific mining, to make details like stairs, instead of massive 4x4x4 holes, they will not min that block above them, making it rather hard to do a lot of things I’d like to do.
(Side note, it also bothers me that we can’t place back stone/dirt/grass, like what if we want the area to look natural, and like, accidentally mined a spot or something…)
