I have a 2 retainers, one I chose to be a miner/gatherer, hes fine and has been receiving experience no problem. He is the second retainer on my list. For first mission I chose Highland Exploration I, he came back and exp got him from 1 up to 9.

The other (first on list) I chose to be a conjurer, sent on a Field Exploration I, she came back, and exp went from 1 - 8. Thought that was a bit fishy but sent her off again. Next time she came back, items but no exp. Checked her character page and exp was sitting at 0/7350. Sent her on a quick mission then for 1 hr, came back, items again but no exp. The exp on the report popup said over 4000, and still she sits at 0/7350.

Anyone else seeing this? Or am I just doing something wrong? She has a level 1 wand equipped, but my miner only had his level 1 pick equipped until I started needing more gathering. It was noted plainly when he needed that, I'm not seeing any notifications for stat requisites for conjurer though.
