This mod overrides inventory whenever an inventory recognized by this mod is not found. I attempted to make a sfinv compatibility layer mod for your mod by adding a page, however, it was buggy. So I overridden the crafting page instead. It can only do this if it overrides one of your mod's functions to prevent the 3d-armor override.

The mod is here.
edit: Hmm... That "bugginess" I'm having trouble with is very much like the issue you are having over at https://github.com/stujones11/minetest-3d_armor/pull/82
