Fixed since 3.3.0:

• A correct mirror between halves built differently (decimated, slid or off-centre) no longer shows false "LOST", "repairable" or "mismatched counterparts" messages, and Quick Fix no longer empties it.

• Mirror All L/R Groups with Interpolate and the cache on no longer leaves holes.

• Topological Mirror keeps its result on posed meshes.

• Mirror in World Space now works on rotated objects.

• Perfect Single Mirror refuses the wrong direction and keeps your painted side.

• Find Own Mirror Plane also tries world space, so imports turned one way with the object turned back mirror correctly.

• Interpolate Symmetrical Weights no longer spills past the painted edge.

• Select Mismatched Vertices selects only the target side.

New:

• An Auto-Adjust Tolerance button under Precision Tolerance.

• Tested on Blender 5.2.2 LTS.
