Stable Surface is a Vintage Story mod by Wafers. Stable Surface removes random unstable patches above sea level while preserving underground stability mechanics, sanity drain, rifts, and storms.
Why this mod is worth installing
Useful for builders and explorers who want predictable surface locations without disabling the deeper survival systems. It is especially helpful when a scenic valley or forest is meant to become a permanent base.
What Stable Surface adds
Stable Surface changes the stability check so that terrain above sea level is treated as stable. This prevents the random surface patches where a placed gear begins spinning and the area becomes unsuitable for construction.
The change is limited to the surface. Underground areas can still affect sanity, while rifts and storms retain their usual behavior, so the mod removes an annoyance rather than flattening the entire stability system.
