Then you know it's working. It didn't load the 1st time because there was a _en at the end. But now you face a new problem. Why is it crashing? Well, I can only assume it's cause of filesize limitations. You can't have too many model imports when it comes to item hacks sad to say...
Hm. I didn't know about the filesize limitations. I'll do some research and see what I can do about that.
Thanks, I'll post updates soon!
