I know this is an old post but thought I should leave this here.
I picked up and updated for Vintage Story 1.22, since DArkHekRoMaNT has paused his mods.
The continuation is here: https://mods.vintagestory.at/show/mod/50572
Same mod from the player's side (config schema and behavior unchanged), rebuilt against 1.22 with CommonLib removed so it now ships as a single self-contained DLL. If you're upgrading, remove the old helvehammerext-*.zip from your Mods folder first; both loaded at the same time will conflict.
