Resolving Errors - Unknown Cook Failure

Development Programming & Scripting Blueprint

I was packaging one of my projects as a test, and after about a day or so the build failed due to an unknown cook error. Looking at the log, it was unable to find one package and then the rest of the errors were from trying to delete intermediate files.

Below is that portion of the cook log:

Reason: Name may not contain the following characters:

The error is clearly in the path used to find the package, but I wanted to find out how I could rectify this in the engine? Also what should I do about the intermediate files?

Try to remove all " " (space) characters in your paths / names …
About deleting files, ensure that you are admin of your computer, and maybe try to delete them manually ?

In a blueprint only project however, where can i modify paths and names? I don’t use the water auto material anywhere

If anybody stumbles upon this, I still haven’t had my question resolved and don’t have permission to remove the resolved mark.
