What happened?

Trying to use missing_block_ids.json5 to replace a block with a block from a mod loaded after blockswap makes the server crash at startup. Fabric seems to load mods in alphabetical order - and the order can't be changed - so this means blocks from mods that sort after 'blockswap' can't be used.

In the attached log, I'm trying to replace a block from vanilla with a block from swampier_swamps, but when blockswap loads and dumps the registry, swampier_swamps hasn't been loaded yet, its blocks aren't in the registry, and the server crashes.

A possible workaround might be to rebuild the blockswap jar locally with a 'z' at the start of the mod ID, to force it to load last, but I haven't tried it.

Confirmed that changing the mod ID to 'zblockswap' works - fabric loads it last. But using a custom version depending on fabric's undocumented load order feels very fragile - especially when fabric doesn't provide any load-order-management tools to the user.

Is there a way to make the config load lazily, so it isn't load-order dependent? Or to initially load the replacement blocks as strings, and only later look them up in the registry?
