The guildspell: Have Group, Will Travel, to summon all part/raid members doesn't seem to work on cross-realm characters (after using the LFG tool)

This is the first time I was using this spell, so this is under the assumption the spell is actually working as intended in other cases.



Groupmembers targetted for the spell on different realms were getting nothing at all indicating that the spell was being used (like a dialogue box asking whether you want to be summoned or not etc)
