Hi i don't know if it is a bug or problem really but when you train in spell doesn't the spell pop up in the face of the person playing the wizard? i don't know if there is an option to change it from in the face to a floating picture of a spell card that vanishes after 10 seconds. Thanks for your help.
If your talking about from Loremaster, yes it usually pops up on the top of your screen. I also agree the length of time it is there should be a tad longer, however that being said the spell will also show up in your deck as many times as your deck allows it, so there is not really any way you can miss it.
The recent update now sees spell learned popping up as a drop would when defeating a mob. It no longer pops up in your face unless it's a crafted spell.
Currently, there's no option to reverse this.
So, no, it's not a bug. It's completely normal.
You will see the spell in your spell book as you will the others.
