I was in the middle of a handwritten message on miiverse, when my drawing seemed to disappear. I am certain I did not hit the cancel button, as the most of the options have locked up. I cannot continue drawing.
If I try to post the message, the screen turns white and there is an error that says "400 bad request". This would not bother me if it had just happened once, but I have had this problem daily for the past three days. It seems to occur when I draw a picture that takes twenty minutes or longer, which is frustrating because the picture wasn't recovered when I tried to restart miiverse.
This error is starting to really bother me; if anybody could help I would appriciate it.
