Retainer capped at level 79 despite character being 80 in that job
Character: Rydia Mystt@Ultros
Retainer: Shyyyo-bird
One of my Rydia alt's retainers seems to be capped at level 79 summoner despite the fact that Rydia is level 80 as summoner. Shyyyo-bird has been level 79 for a couple of months now despite continuing to send her out on ventures.
Her other two retainers, Shrunken-justin and Artikodin-articuno are unaffected. Those two retainers are level 80 summoner, Shyyyo-bird will not go above 79.
With my main, Moltres Rider, it only took five days of sending retainers on ventures to get them from 79 to 80. This includes when I decided to purchase a third retainer, jump him to 70, and leveled him to 80. He took only five days as well to go from 79 to 80.
Shyyyo-bird is constantly going on ventures like all the other retainers yet will not level above 79 no matter how many ventures she goes on.
Rydia has not touched any other job and every other job is at where they started. So she definitely does not have a different job at 79. Besides, all three retainers have the summoner icon.
Does anybody know what the problem could be?
