Hello, I'm a new MoI user. I installed the object library script so that I can start saving the kits I built however, I'm having an issue saving the object in the library. I attached a video to show what I mean. I'm using windows 10. Can anybody help me?

Oh and also if anyone knows a better way to attach videos onto forum, than to having to download onto the computer, that would be great!
