The modify_player_spawn power type doesn't function, and errors in the log that the dimension it attempts to spawn the player in is not in the registry. This affects Blazeborn by default, but any origin using this power type will also spawn in the Overworld instead of the intended spawn.

This is such a weird issue; it seems like vanilla dimensions are not being registered in the dynamic registry for dimensions on world creation screen at all, as it's empty (I checked on SaveLoading#load.) It'll only be occupied if there are data packs that either include custom dimensions, or overrides the vanilla ones (like Terralith)

The only solution I can think of is to do some sort of "whitelist" for vanilla dimensions, so that powers (or any reloadable data that uses Calio for serialization) won't throw the error if it's specified 🤔
