Yeah, so I’ve done basic troubleshooting stuff. Reload file, apply transforms etc. I would think bug, but it’s very consistent, uniform and not reacting in a buggy way. Which is what makes me lean towards some setting. Anybody know of a setting that identifies a selectable area in a mesh?
And as quickly as it came it left… Tried adding another mesh into the scene, entered edit mode, back to object, deleted the 2nd mesh, and first one worked. I think this may be left a mystery but we’re back in business. Looks like a bug after all.
