I am also on level 80 and the clock says I have 70 hours left, it has been saying that for three days now. So far, I have not seen an answer or a fix for this on King.Care, they keep asking if we have changed our clocks on the devices. NO ONE has done this, and yet King.Care obviously does not care, since it has not been fixed.
I stopped playing two years ago, when the big data dump happened during an "upgrade" obviously, King has not gotten any better with customer support. Unless this is fixed, I will dump the game and never open another King game!!
