the dynamic type bevy_reflect::DynamicStruct (representing glam::IVec2) does not support hashing

[Liam19]

As the title suggests, I'm getting this error when updating my project to Bevy 0.15.0. This error occurs when trying to use DynamicScene::write_to_world(). I can't find/understand any of the reflection migration guides for 0.15.0, so am I doing something wrong? This was working in 0.14.2.

use a HashMap<IVec2, ()> instead of a HashSet
