I recently updated from a 2017 build of Unity to 2020.1.13f1, and I’ve noticed the editor inappropriately replacing the first character of file names with an underscore upon importing them into the editor. Two examples:
- I dragged-and-dropped Sparkle.png into the Project, and the editor renamed it to _parkle
- I dragged-and-dropped Classes.xml into the Project, and the editor renamed it to _lasses
This is deeply annoying and actively slows down my workflow. It has only happened to me in Unity 2020.1.13f1.
