Minecraft Version

1.18.2

Immersive Engineering Version

8.4.0-161

Immersive Petroleum Version

4.1.0-19

Current Behaviour

When a datapack is loaded with either KubeJS, Openloader, or the Minecraft built-in datapack loader, files in the datapack that are structured to override files in Immersive Petroleum's internal datapack file structure, will not override. Tested with both recipe JSONs and Structure NBT data.

Expected Behaviour

Files are supposed to override properly and recipes and/or structures should be changed accordingly.

Reproduction Steps

1. Create a datapack for Minecraft 1.18.2 that has inside it the same datapack file structure that the Immersive Petroleum Jar has.
2. Create a recipe JSON with the same name and function as a recipe JSON in the same corresponding file location in the Immersive Petroleum Jar.
3. Modify the recipe JSON to differentiate it from the original recipe JSON it is intended to override.
4. Load the datapack into Minecraft.
5. View the target recipe in JEI to see if it changed accordingly.

can you add an example of a changed datapack for testing? (including exact location where you put it and a screenshot "how" you have enabled it inside the client)

Yes, Here is a test datapack to use. https://github.com/jmarchant22/Immersive-Petroleum-Custom-Datapack-JAM-28APR23.git
The oil distillation tower should be changed, and the lubricant cracking and naphtha cracking hydrotreater recipes should also be changed. The distillation tower multiblock should be changed to using silver sheetmetal instead of iron sheetmetal.

Full paths of every folder inside that data folder
in text form please...

Edit: And make sure everything is lower-case

Distillation Tower Oil Recipe:

"~\data\immersivepetroleum\recipes\distillationtower\oil.json"

Hydrotreater Recipes:

"~\data\immersivepetroleum\recipes\hydrotreater\lubricant_cracking.json"

"~\data\immersivepetroleum\recipes\hydrotreater\naphtha_cracking.json"

Distillation Tower NBT Structure:

"~\data\immersivepetroleum\structures\multiblocks\distillationtower.nbt"

Thats on your end. (Probably KubeJS being the fault, try removing that)
I've got it working on my end without having done anything to the datapack you provided.

And the HPRU's secondary_input only accepts tag and not fluid. (Hydrotreater)
Those wont even work because of it and will drop a com.google.gson.JsonSyntaxException: Missing tag, expected to find a string error in the logs.

_{PS: Structure files require either a full game restart or world-reload btw}

Confirmed, it is one of my KubjeJS scripts. Will add one more comment which will show the solution, in case anyone stumbles upon this in the future.

All my KubeJS scripts appear to be fine, and the structure is now loading properly. Closing this issue.
