Since that variable's not defined in the add-on, it gets set up as a type of "nil" and passes without issue until another one of its kind shows up and it tries to figure out where to insert it under the other wise safe assumption that type is a number and thus is breaks when more than one guild invite pops up. I attached a copy of the code file with this fixed.
