Issue ID
1314594
Regression
Yes
Not all 2D sprites get imported when upgrading a project from 2018.4
How to reproduce:
1. Open the project "FixTilesetBug.zip"
2. Extract the archive "TextureThatImportsWrong.zip"
3. Open the extracted texture "FoothillsGround0.png" in the Inspector
4. Observe the number of sprites (7)
Expected result: Texture is still divided into 11 sprites after upgrading the project
Actual result: Some sprites are missing
Reproducible with: 2019.3.0a1, 2019.4.20f1, 2020.2.5f1, 2021.1.0b7, 2021.2.0a4
Not reproducible with: 2018.4.32f1, 2019.2.21f1
Notes:
You can see the expected and actual result in the attached images

Thanks very much for helping track this down. I'm sorry that this was an issue on my end - these spaces are from an importer we wrote over a year ago to generate PhysicsShapes. Looks like we wrote this before 2018.4 introduced https://docs.unity3d.com/ScriptReference/Sprite.OverridePhysicsShape.html
Again, apologies. I hope it wasn't too hard to track down, as this helped me immensely in finding the bug on my end.

- ADB PRovider is really slow
- "System.Net.CookieContainer" throws an "ArgumentException" error when using a non-UTF-8 machine locale and hostname
- Crash on ModelImporter::ImportSkinnedMesh when disabling "Strip Bones" on a specific FBX model
- WebGL Development builds ignore the "Compression Format" setting when using "Gzip" compression
- [tvOS] Project crashes on startup on Apple TV simulator (both X86_64 and ARM64 architectures)
Resolution Note (2021.2.X):
The issue is caused by extra blank lines being inserted in the meta file of the .png file after physicsShape. As far as we can tell those extra blank lines are not produced by Unity and are not supported by UnityYaml introduced in Unity 2019.3. To fix the sprites with this behaviour you can remove the empty lines in the meta file prior to the upgrade.
