Went into three different delves in Cyrodiil and killed the bosses in each. Never received credit. The delves were Toadstool Hollow, Ruby Red and Quickwater Cave.
In Quickwater Cave I killed the boss three times. In addition, once I left the delves their locations disappear off my game map. The only way to find them again was to find a interactive map of Cyrodiili on the internet and then cross reference there locations via keep reference points on my map. I am so glad this game went F2P. I would not waste another dime on this bug riddened game. Whats really aggravating is that every patch or update ZOS implements just creates more issues and bugs.
