Issue ID




GameObjects mesh is stuck at Combined Mesh (root:scene) and cannot be moved after aborting a build process

Graphics - General


1. Download attached project "Sand_6_v2"
2. Open scene "Scene 1"
3. Notice that it contains a lot of game objects. That's the same game object cloned multiple times and purpose of this is to ease repro as it's all about timing
4. Open build settings, press build and run, enter scene name and tap enter
5. Quickly cancel build before new blank scene gets opened (as per usual build process)
6. Expand any GameObject and notice that all mesh filters are stuck with combined meshes

Reproducible with: 5.5.0f3, 5.5.4p2, 5.6.0f2, 5.6.2p4
Not reproducible with - 2017.1.0a3

1. Probably not the only way to reproduce the bug, other users are experiencing this issue after downgrading, light baking or etc
2. Can't reproduce the issue with 5.4 version of Unity, since the project gets corrupted and couldn't cause the issue with my own project

Fixed in 5.6.3p2

    Just happened to my project in Unity 5.6.0p4
    Really really frustrating... Please fix. This IS an highly critical bug.

    Still happening, having to replace every static mesh is taking me hours.

    Just had the privilege of encountering this illustrious bug. Thank god damage was limited by reverting to an older version of the scene & prefab.

    Unless you backup your projects frequently this is a serious bug that can destroy the whole mesh / light in your project.
    Make sure you never abort a build process.

    this may not be a build issue, other than when assets are imported into the new version.
