Attack/Move commands not working

For the past week, I would click to move or click to attack a minion and Nothing would happen. I would, for example, click next to bot tower, and while I'm on my way, I would click to mid lane. The game still has me going towards bot tower but would not correct itself given enough time. I get the blue marker of clicking but I would not go there. The white line on the mini map still has me going bot. My frame rate would not drop and my png would not increase so its not lag or a frame rate issue. It has been happening quite a lot (and I've died multiple times while this was happening). Please Help!
