@Azanor Perhaps we replace the golems with spells? Could set up a chopping spell around an area of trees which chops them when activated, you then set up an overlapping teleport spell which teleports the wood to above a hungry chest. This way you avoid having entities completely, all you'd need is a sort of arcane redstone system. All these could be powered using vis. Could have it work like a foci block that takes a redstone signal, and then make the relevant focis craftable. Would be a shame losing golems but think this would be a thematically fitting way of solving the issues you're having.
Noooooooooooooooo, I love my golems!
