Zmodeler - Attaching/Adding a Divider (RC20 Error)

I am having a problem adding a divider/partition to a new vehicle I'm working on. I've tried putting it in different places within the hierarchy as well as attaching it to the chassis as I have in the past and it's worked fine. When it's placed under another dummy it has the proper misc_* name but that doesn't work. I've attached it to chassis and just for attempts for that not working I've also attached it to bodyshell. That's also how I've seen other models come with the divider attached to the chassis. It keeps crashing me out whenever I spawn it in game and giving me the RC20 error. When I take it out/take a step backwards and have everything else on the car installed it works just fine. It seems to be the divider that is giving me that problem. This is the last thing I need to make the vehicle complete and it's driving me crazy. Any help or suggestions would be highly appreciated. Thanks in advance!
