Describe your issue

I know that using large packs is probably not supported with alpha versions (in which case, I apologize, but I wanted to try it out in a more realistic scenario rather than isolated) but installing TC into my private modpack causes KubeJS to no longer load recipes.
Reloading KubeJS using /reload works though, so there's just something wrong with the initial load. Modifying any recipe, as seen in the example I've provided in "Other mods", makes KJS fail to load w/ TC.

Other mods

TC same ver, Mantle same ver, JEI 15.20.0.105 (same version), KubeJS 2001.6.5-build.16, Architectury 9.2.14, Rhino 2001.2.3-build.6.
in the testing instance isolated from the modpack, a test script in kubejs/server_scripts/example.js:

ServerEvents.recipes(event => {
     event.remove({output: 'minecraft:blaze_powder'})
})

Tried reproducing with just Tinkers?

Yes

You can disable KubeJS running recipe stuff in parallel by setting allowAsyncStreams to false in kubejs/config/common.properties. That should resolve this.

Thanks for the temporary solution :-)

Seems that not everything in Mantle's tag preference system is fully multithread safe. Most of it is but I missed one spot. Should be an easy enough fix.
