My prepared spells on one particular character:

Seem to disappear at random. At this moment, I have 1 out of the 9 that I picked last night. Sometimes, I will log in and one or two will be missing, sometimes almost all will be missing.

I don't mind recreating the character, just an annoyance that I thought I'd bring up.

We will make sure that the staff give a look at this. Thanks.

Seems to be affected by the same issue. I think it might be related to leveling up, choosing options, then downleveling that character.

My Wizard is also having the exact same issue. Everytime the page refreshes, I lose all prepared spells:

Only my Wizard has this issue, the Priest is unaffected. This was also working perfectly prior to Saturday.

Same thing is happening to my druid. She was in Circle of the Land, then I switched to Circle of the Shepard. Ever since then, she can't retain some spells.

Mine just suddenly corrected itself, so maybe they're looking at this one.

This is fixed now.

Thanks!

I also am having trouble preparing spells for my wizard...they show as learned, but I am unable to "prepare" them...

I too am having trouble preparing spells. It looks like its counting my cantrips towards my prepared spell list. 

Im having this problem with my wizard, when I export the character sheet.
