I get this msg everytime I play. Happens mostly at almost any cm, storage container, world boss battles. Basically anywhere a group of adventures gather. Sometimes I can avoid it by running to cm or storage and do a quick exange then run away as fast as I can. As for world bosses I have found that shutting down game completely and restarting 15 min before battle usually will keep this msg at bay. Hope this helps. Is the only game I have to do this kinda thing for.
