60 Fixes the error msg but should in this case the field be added to the list of fields or not? For which type of field does that happen? - the configuration array is a beast :D and the same beast is this nasty function to get all fields that mach the field connection :D
Haven't got the time to actually debug this, just found the notice and I always use pods_v for getting field/pod data since the huge config arrays aren't reliable.
