Help with 'Error: Resource not found: NULL'

[smbrannan]

I am trying to create my own faction, but when I let Armored Brigade automatically select units for a game, it gives me this message, and the program shuts down: 'ERROR: Resource not found: NULL'. When I select the units automatically, it works fine. At first I suspected I might not have units available in every category, like infantry, mechanized, etc, but that is not the case.

I searched for information but I have not found any other posts on this subject- if I missed something please let me know. Otherwise, can anyone help me fix this error message? I can post the edited database I am using if needed. Thank you in advance.

Never mind- the problem was I had the default NULL remaining for some of the sprites of a few units I created. Once I corrected that, I stopped having the issue.
