There is again errors in tipping/upvoting! I upvoted an article, and the BCH amount was deducted from my wallet, but it didn't show my profile pic as an upvoter on the article's upvote display! 
Oh my... Hope it gets fixed by someone.
The amount has come back to my wallet after many days :)
Yeah i encounter as well but all of tye sudden it went back to normal maybe there is something doing innthe system
