How to reproduce:
1. Open the project “IN-103109_FileID-22.3.55f1-Before-Regression” as 2022.3.56f1 (or newer)
2. In the Hierarchy, click on “fx_monster_item_trail_01” → “p”
3. In the Inspector, navigate to Particle System → Texture Sheet Animation → Mode
4. Observe the Mode list of Sprites
Expected result: The Sprites are assigned, entering Play Mode also produces Particles that look like gems
Actual result: The Sprites are missing, entering Play Mode also produces Particles that look like white squares
Reproducible with: 2022.3.56f1, 2022.3.63f1, 6000.0.24f1, 6000.0.51f1, 6000.1.9f1, 6000.2.0b7, 6000.3.0a1
Not reproducible with: 2021.3.53f1, 2022.3.55f1, 6000.0.23f1 (1c4764c07fb4)
Reproducible on: Windows 11
Not reproducible on: No other environments tested
Notes:
- Downgrading the project to the “Before-Regression” versions (2022.3.55f1, 6000.0.23f1 and below) reassigns the Sprites
- FileID changes in the prefab metadata when manually relinking the Sprite resources
