The Valheim Plus mod has both advanced building & editing modes. ABM allows one to rotate building items in any direction when first placing them, and the editing mode allows one to move building items after they have been placed. Valheim Plus developers always update the mod within hours of a game update and are always fine tuning the mod based on reports by users of any bugs. Valheim Plus is an excellent, stable mod that does almost everything, and the best thing is it is always kept up to date. When using any mod, no matter how trustworthy, always consistently perform manual saves.
