There appears to be a problem with detecting/rendering OreDict entries that were created by mods. I am using PrimalCore along with a few other mods and this is a sample of guidebook xml demonstrating variations of the issue:

<big_recipe>
<stack ore="blockDrain"/>
<stack ore="toolAxe"/>
<stack ore="plankWood"/>
<space/>
<space/>
<space/>
<stack item="primal:drain_thatch"/>
<stack item="primal:flint_axe"/>
<space/>
<stack item="primal:worktable_shelf" meta="2"/>
</big_recipe>

• The ore="blockDrain" cycles through the items but they all have missing textures.
• The ore="toolAxe" does not show anything at all and fails to find the many axes with this label.
• The ore="plankWood" successfully detects the new versions of planks that the mod added so there is no issue with this.
• If I instead use item="primal:drain_thatch", it does display the drain's texture.
• If I instead use item="primal:flint_axe", it does find the axe and display it correctly.
