I fixed it! Thanks for the report

It's not fixed.
A harvester will call minetest.set_node with a node called "ethereal:strawberry 2" wich does not exist and is against naming conventions.

see

techpack/tubelib_addons1/nodes.lua

Line 128 in 289fa75

fn("ethereal:strawberry_8", "ethereal:strawberry 2", "ethereal:strawberry_1")

I was too hasty. My fault.
It registers to drop two of ethereal:strawberry and plants a ethereal:strawberry_1.
