As the header suggests, using a long rope, tree, and leather mat, I full-butchered a full tile-stack of zombies, which suggested it required 9 hours.
Attempting to stop queries the [Y/N], however, prompting the [Y] response after a few hours in failed to stop the process and it continued anyways until deep into the night.
I have confirmed that this has occurred more than once, happening twice. Since then, I butcher by the corpse instead of the full-stack option to avoid wrecking my character’s health stat.
Version is from November 20th, 2019.
No mods or alterations. Default settings across the board.
The only change was adding a tilepack.
