Hanging on Forcing Save Package - UT Editor

Hi everybody, relatively new to the UT editor and brand new to the forums(as this is the first issue I haven’t been able to youtube my way out of hah)

When I try to package my level it hangs up on “Forcing Save Package” on modified/custom assets related to my custom weapon.
I took out the weapon and packaged successfully so I think I’ve narrowed it down to a handful of files that the weapon is referencing.

If this was the file path, would that be an issue?
UnrealTournament/Content/RestrictedAssets/Proto/UT3_Weapons/WP_BioRifle/Materials/M_BioPAINTBALLyellow.uasset

Am I just not allowed to use assets in the RestrictedAssets folder even when I completely change them?
Can I go back in and move the files to another folder?
If so which folder is safe?
Is it something else completely?

I’m at a loss here, any help is appreciated, thanks in advance!
