Adding a nodal load to an RBE2 spider not working

Hi, 

I am analyzing a pipe with flanged ends and I am using one spider to connect all the bolt holes. I am applying several reaction forces from a connecting piece of equipment then adding those loads with LoadADD card. I can add one moment, but then when activating other load collectors for the point loads the node can be selected (turns orange), but i create the point load on the node it turns grey and nothing happens. Can you apply multiple loads to a single spider node?
