Bug with derby task restarting when completing!

[Sarah2813]

I completed my back derby task (collect 65 bacon) however, as the points were added to the score, that same task was selected again, but with only the remaining time from the previous task??? I did not select a task at all! I then tried to trash this strange task and it counted as 1 or my 5 tasks

My case is worse : even after completing my task.. I did not receive my points.. And supercell isn't responding to these bugs..
