# GriefPrevention3D v18.3.7
**Wiki:** https://github.com/castledking/GriefPrevention3D/wiki
## Overview
This is a fix release for the shaped claim cuts introduced in v18.3.6. Cut clicks only worked
when every click landed at the same Y level; otherwise the path failed to close and players saw
**"The resulting shape is not valid"**.
## Root cause
Cut click classification used the claim's 3D containment check
(`claim.contains(location, ...)`), which requires the clicked block's Y to fall inside the
claim's height range. Shaped claims are 2D — their geometry lives entirely in the X/Z plane — so
a player clicking on terrain above or below that band produced a point that counted as neither
interior nor boundary. The cut path could then never detect closure, and finalization rejected
the shape.
## Fix
All six cut-flow classification checks now test the click's X/Z coordinates against the boundary
polygon directly (`polygon.containsCell(x, z)`) instead of the 3D location check:
- interior-cut-click detection (both handler paths);
- general interior-click detection;
- boundary-closure detection (clicking back onto the boundary to finish the cut).
Y level no longer plays any role in shaped claim cuts: you can seed, shape, and close a cut from
any elevation.
## Upgrade notes
No configuration, storage, or migration changes. Drop-in replacement for v18.3.6.
