v2.1.2 ProceduralParts for KSP 1.8+
Bugfix release, with support for SmartParts.
Bugfix: SeekVolume directly sets field values for symmetry counterparts. Previously, an external tool that wanted to request ProcParts set the volume would only apply a new length to the active part in any symmetry group, but still shift the attachment nodes to all parts in the group.
