At least, no one will ever post or reply "it is because of OoW launch" on the Agnarr server... We can scientifically exclude GoD or OoW release as explanation of current bugs !
If you think there aren't any relationships between the servers that might cause bugs, even if the affected server doesn't have the expansions in question... Well I have a bridge spanning the realms of discord and Norrath to sell you, on Agnarr. Only a million kronos.
