"Warning: Unused Data" Frequent Error Preventing Launch

[TheSneakyHooker]

Hi everybody,

 

I added roughly 70 mods to FO4 using NMM, I ran it with FO4Edit the other day and got beautiful results, no problems, game ran fine with the mods. I installed one or two since then, not even large mods if I remember correctly, just simple textures and stuff. Now, I'm getting tons of "unused data errors' and my game won't even boot up.

 

If you know how to use FO4Edit and interpret it's errors, please help me out in figuring out what is wrong. The load order will be pasted below and the FO4edit log will be a document attached. Just by intuition I'd say the problem is load order or missing compatibility patches...

Those mod authors used (or still using) old builds of FO4Edit that didn't handle OMOD records correctly, there was a warning on FO4Edit page about that but they ignored it. To fix that select those records with errors, right click, mark as modified, exit and save.

After about 12 hours of troubleshooting, completely removing NMM and FO4 and reinstalling both, I found that a single mod, "No Perk Level Requirements', was the cause of all of these issues. I downloaded a patch that prevented it's crash on startup from that mod, game finally runs.

Me Too. So happy to see this as a fixable problem. Just be sure to be able to reinstall the .esp if you get a "stream error". that means there is an entry giving an error like "Expecting data found none". Just marking that modified without fixing it (either overwrite or delete) will break the .esp and you will not be able to load it again to fix it. Not sure how that will affect the resulting mod but if they were errors I expect it will only be more stable.
