sometimes when i play my lasthits (x) and clear (v) and combo either, and after some time its working normal but then it happens again, i deleted config in appdata but its still the same problem.
you can either delete all the files or use another config
if you want to delete press win key and R type %appdata% you will find file called LPRB delete that and try again
if you have config just replace LPRB with the config files and you all set
