D Series body disappearances.

So, after messing with the D-Series's bullbar, I had a problem. all of the models stored in pickup.dae weren't showing up in-game. The jbeam for it was still there, but the model was gone. I removed my mod. still broke. I deactivated the mods that concern the D-Series. Still broken. I deactivated all mods. Still broken. I deleted the pickup ZIP file from content\vehicles, and used steam to verify integrity of game files. Still broken. Attached is the zip file. Any ideas?

 

But I let steam completely replace the pickup.zip file, and removed my mod for it from the mods folder. I also deactivated all other mods. the pickup.dae file should be completely standard, unless steam messed up somewhere. I checked this, and it seems perfectly normal.

 

Deleting that and letting the game replace it fixed the problem. Thanks!
