Is it possible to have a mixin in a file that you’re then using your manifest to mixinto another mod’s file and override/remove anything in the other mod’s file? It seems like when I try doing it, the `mixintype` stuff doesn’t get applied, and I’m thinking that it gets applied and then removed on the first mixin—the mixin specified within that json file itself—and then is no longer there to get applied when the manifest mixes it into the other mod’s file.

I’ll try to give a specific example to explain:

I want my `bronze_sword.json` to be mixed into the base game’s `bronze_sword.json`, with one or two `mixintypes` overrides. However, my `bronze_sword.json` specifies a mixin of my `weapon.json`. It seems like the `mixintypes` get “consumed” on that initial mixin and aren’t around when the manifest mixes the result into the base game JSON. I tried specifying the base game JSON as one of the mixins and then making it an override in the manifest instead of a mixinto, and that just instantly crashes the game.

I also tried abstracting it one level: I made a `bronze_sword_mixin.json` file that only contained `"mixins"` of both my `weapon.json` and `bronze_sword.json` and then specified `"type": "entity"`, and had the manifest use _that_ as the `mixinto` for the base game `bronze_sword.json`; that had the same failed `mixintypes` result as the original strategy.
