I saved them to user missions then hit save as and exported them to multiplayer missions.

I created three missions and they all work fine in preview but when i go to have a friend join they get kicked from the lobby and soon as they join. This only happens too two of the three missions i made. I can play all the missions myself so i dont understand why i cant have someone join. Also when loading all missions in the editor i get this error message " mission contains bad link to a static object. Open it in the editor and save it again." Thanks in advance I've looked everywhere but found nothing.
