server 17 Heart Of Dragons here too. We have not noticed any bugs with guild wars except for a number of disconnects and failure to sync with server errors experienced by several guildies, causing them to miss command stages. However, we do not control any cities, and are merely challenging (and losing...lol!). Most errors we have besides the server disconnects (which seem to happen in EVERY event now) are all human errors and caused by just learning how guild wars work on Tynon. *shrugs*
