UPDATE: It appears to be a mod causing this. They worked in safe mode. The default D-Series can load, but so far I haven't been able to load the Roamer at all because of this. I checked the common directory, and the files the error message mentions (trim_d.dds, trim_n.dds, and trim_s.dds) are there. I know for a fact mods isn't doing this, I don't have any mods that alter any major files for these two vehicles. I have skin files, but that doesn't seem to break anything. I was able to load a skin for the D-Series, and it didn't break. It was these two configurations that I tried to load that triggered the error message.
