Units uncontrollable during some matches

In the last 3 or 4 days a few matches have been weird to say the least. After playing this game for over 2 months my units have been uncontrollable in some matches recently and by uncontrollable i mean when i attempt to click on a unit it dosent register or i did click on him and he was selected but the previous unit moves instead the, first time it happened i thought maybe i needed sleep lol but it happened a couple more times and im wondering if anybody knows what is going on is this a new hack? My network has been the same either 4g or a strong cable wifi so the network has not changed nor do i think this is related to an update im running a note 8 if that help and if this is because of hacking i have the names written down and replays saved if need be
