There are (or were) a number of unfortunate placeholder screens that cause confusion. For example in the daily quests the placeholder screen that you get with no connection, or during loading has some random quests on it. It's just an image not a real set of quests. They should change these to show a 'loading' or 'no connection' message... but I bet that's what's going on here too.
okay made a test to see if it was my mobile but it works find on it.
what i get from that is i am stuck in the tutorial after you get your heal spell and before you you put your first item on. it might be that the game did not give me a item to use and now i am stuck with not being able to do the mission/tutorial
also it seem the change to my class did nothing to help this
If you are unlucky as i am, you end up with the same item 5-6 times in your inventory.
Selling them one by one is really slow.
Having to remember how much you have those items to be able to set the sell number -1 is also not good.
Suggestion: Make character slots to lock your items so you will don't sell those items by accident like me.
