New error seen after winning matches

[Caerold]

I got the same error message four times in the last 2 days, under slightly different conditions but (I think) while I was fighting in a tournament each time.

Warning
There was an error while saving your reward


I took screenshots but I can't get the links to work on the board

Hi,

I doubt it, this will happen in tournament battles. There are no rewards...
Can you give me more details about the circumstances when it happens?
Do you dismiss the reward window as quickly as possible?
Does it happen when you play against AI or against another player?
