Seemingly random Infusion recipes are broken

[RaidhoSketch]

Says to look into the log, in chat, in red. So, here it is:

fml-client-latest.log

Hmmm. Switching out AspectRecipeIndex for the previous TCNEIAdditions makes the same error.

Okay, this is straight-up bizarre, but this is likely the only place where we could find help, so.
Removing both Thaumic Bases and Ye Gamol Chattels from our pack fixes it.
And this is not reproducible on a clean instance with just those.
In any case, hoping for some attention, here.

Clean-instance-testing it proves to be one of the hardest bugs to root out the reason for.
Iteration one, with both Bases and Chattels: it snags on adding RotaryCraft.
Iteration two, with RotaryCraft as well, the error starts after adding Netherlicious.
What the actual heck. Here, have another fml log snippet.

[RaidhoSketch]

Iteration three snagged on Thaumic Energistics, with much the same result.
It appears that this error just... happens, once the amount of mods reaches some critical mass.

[RaidhoSketch]

Same thing happens when trying to look up all Infusion recipes, by the way.

[RaidhoSketch]

We have no idea what (mostly) fixed it, but the log-swearing doesn't happen when viewing individual items anymore, only "all recipes" still continues to not function.

Upd: now the Thaumium Fortress Helmet is broken, along with Magic and Essentia Mirrors, Pech's Curse and Portable Hole foci. Wtf.

I'm investigating this. It seems to be a problem with TC4RecipeLib (one of the dependencies) based on the stack traces you provided.
