Changing a researchPrerequisite in Vegetable Garden using a patch doesn't work

[PartyCowboy]

Hi, I'm trying to make a patch for Vegetable Garden that changes the researchPrerequisite for the RecipeDef "VG_MakebulkPemmican", but it doesn't work, any way I tried.

Here's the code I tried using:

Code Select Expand

<!--Reaaally weird thing. I had to remove it first, before inserting the one of my own, which is exactly the same, but with a different researchPrerequisite...
    <li Class="PatchOperationReplace">
    <xpath>*/RecipeDef[defName = "VG_MakebulkPemmican"]/researchPrerequisite</xpath>
    <value>
    <researchPrerequisite>TS_PrimitiveCooking</researchPrerequisite>
    </value>
    </li>-->
<li Class="PatchOperationRemove">
<xpath>*/RecipeDef[defName = "VG_MakebulkPemmican"]</xpath>
</li>
<li Class="PatchOperationInsert">
<xpath>*/RecipeDef</xpath>
<value>
    <RecipeDef Name="MakePemmican">

<!--End of weird bit and it still doesn't work :(-->

As you can see, I first tried doing it with a PatchOperationReplace, but this error popped up:
Could not resolve cross-reference: No Verse.ResearchProjectDef named Pemmican found to give to Verse.RecipeDef VG_MakebulkPemmican

Then I tried doing it the roundabout way by first removing it, then putting it back in, except with the researchPrerequisite changed, but then the same error popped up again!

I am baffled as to why it won't work, since I've done it dozens of times for other mods...
I appreciate any and all who have a solution for this.
Thanks

Okay, never mind. I screwed up my file structure...
