Godot aims to be as version-control-friendly as possible, and contributors are well aware of several issues related to sporadic resource ID changes. In this snapshot we’re shipping one of the fixes that aims to address the issue (GH-65011). Related to this, multiple problems with renamed and moved files causing crashes and scene corruption have been fixed (GH-80503, GH-81657).
Very nice. I always wondered if it was something I did or just Godot feeling like changing ids in scenes around.
