Hey there,
I think I discovered the solution to my previous problems, but now of COURSE a new one has arisen…lol.
Despite my mod saying it has successfully cooked out, it has not. I manually verified with my own eyes that it is NOT cooking out anything other than the GenericMod.umap.
Anyone? /cry
UPDATE: PROBLEM SOLVED. Read thread for fix.
I may have found a solution for you, because it seems I’ve been having the same problems myself until just a few minutes ago. I sent you a pm. I’ll make a short tutorial if all goes well in the end for anyone else having the same problem (not cooking properly but everything works like a charm within the Dev Kit).
I think i may be having the same issue. My mod works perfectly in the editor but once cooked out I can’t get it to load in game
ARKDevKit\ModTools\Output\DeadFindx\CookedMods\YourMod
Make sure that it’s properly cooked out by following the path above. It should have the same amount of assets that you are working with. If not then you need to rename your mod file names. So PrimalData_BP_GenericMod needs to be renamed to GenericMod_PrimalData_BP (Or anything you want). And that goes for ever mod, and then cook/upload and have a good day =D.
Do I have to rename everything related to the mod? Child BP’s custom textures etc?
As you know I tried this, and initially this worked. But now after having to make updates it is NOT cooking out ANY changes yet again even after renaming. Really not having fun here.
Delete the output to see what’s updating and what’s not updating. Every time I had to make a major change I deleted the entire output folder of my mod to make sure it was working properly.
Did you try renaming your files?
Did you try changing the name of your mod folder to something else?
Same here. Hoping for suggestions/fixes to be able to upload mod.
Yes and yes. It’s inconsistant.
Darn, that’s really weird. Did you make sure all the blueprint references that you modified is in your mod folder?
Yup. Cook number (legit) 37 and still not working. Worked the one or two times, but now it won’t. Holy **** this is infuriating. And all the staff is MIA with no answers to this issue 
Sorry dude, once I figured out what I was doing wrong I’ve been able to get everything to cook/upload for me. Seems like it deals with bad referencing/the names of the BPs for some odd reason. The only other method (which I haven’t tried) would just be to manually copy and paste your assets into the cooked output folder where your mod.info is and then upload it from the DevKit and see if that route works.
I was going to try that if nothing else worked. But the last thing I tried worked so I haven’t gotten around to testing it.
All good Shadow, it’s not your fault 
I’m just exasperated at this point and burning myself out on modding without even being able to mod…ironically.
I know how that feels indefinitely. If my mod didn’t work today I was just gonna say screw it and Uninstall UE for just wasting my time.
Well I guess I’m just going to work on actual modding, instead of trying to fix something that is clearly out of my grasp at this point.
Trying one more thing real fast to see if this theory I have is valid, and it looks like it is. I’ll report back with more details in a bit.
Fingers crossed on that attempt man. Not sure what went wrong or how it went wrong after we got it working. But Good luck.
Update: It’s confirmed (my theory that is). If you change the overall mod folder’s name after already having cooked it out even just once & uploaded it, it WILL cause this issue. I managed to get it to cook fully, and then just updated it from there instead of deleting it off the workshop and re-uploading it. Not experiencing any further issues at this time, thank lordy. Also I think part of the problem was having copied duplicates of some things into other mod folders (wanted some things in other mods).
Note: The duplicate BP’s we’re NOT being referenced at all in anything just to be clear, I had made sure it was referencing the BP’s in the CORRECT mod folder.
After doing BOTH of these things I am cooking and updating without any issue thus far.
Awesome man, glad to hear it after all the trouble that you went through to get this far xD.
I FEEL LIKE A BEAST BOBBEH! Just kidding. Thank you for everyone whom helped provide some insight as to where the issue was coming from. I couldn’t of gotten this far without the insight.
