Im talking specifically about the 6 sided logs from back when you had to use world edit to get those blocks, the mod dont know or show those blocks so any old build or old tree schematics, wont work cause the trunk of the tree dont show.

I uploaded a new build (litematica-fabric-1.15.2-0.0.0-dev.20200409.182607.jar) which adds support for converting the old all-bark logs.
