As much as I love this program, a problem I have every time I come back to it is vertices that I never interracted with on the mesh will merge together after working on another part, and ruining the mesh. For example, If I'm retopologizing a bust, and work on the the back of the head, , when I check everything I'll see that parts of the nose and mouth have collapsed edges, and I have NO idea when it happened. At first I saw that it happened if I use relax on the whole mesh, but even when I didn't use relax, random edges whould still colloapse and mess up the topology. Please help!
