Player's heart_core_mat.tres emission_energy_multiplier changes value every time the main scene is saved

[akien-mga]

Every time the main scene is saved, this value in the heart_core_mat.tres material changes:

This messes up the git history but also actually changes the material. Might be a Godot bug, but I'm reporting it here first to debug.

Seen with Godot 4.0.4, and 4.1.1.

[akien-mga]

This seems to be due to the autoplaying Player/model/custom_animations/default_heartbeat.tres which animates this value. Godot will save whichever value is currently shown by the playing animation.

The default setup should likely be to play the RESET animation so nothing changes, and enable idle animations at runtime.

The same problem likely causes most of this diff:
