Cannot load modifier-model

[Keaft]

I'm getting a bunch of "Cannot load modifier-model" errors through a FileNotFoundException.
They start around line 3343: latest.log

illusivesoulworks/constructsarmory#108 is the only other place I've seen this error.

Here is a snippet of one of the errors:

[01:45:21] [Client thread/ERROR]: Cannot load modifier-model conarm:models/item/modifiers/tconevo.draconic_shield_capacity_armor

Do those files need to generate? If so do I need to refresh it somehow?
