Hi There !
Recap: I play on a Singleplayer map. Alone. With 212 mod :D i manually download from curseforge. And since i've unlock the Lumberjack Double Log Skill, e-v-e-r-y block i got, from stone-wood-sand from any tool, i get double one. It's not a "Big" issue but even with the workstations it does double them when i mine them.

And a New Log, exit game then reload and mine/chop blocks to see if it will be in the log.
