Hello,
When i play on my laptop i haven't got great hand-eye co-ordination. I use my Xbox controller instead.
When something happens. Such as, The laptop dying and turning back on. When the laptop goes to sleep and turns back on while Minecraft is running. The controller will stop responding. It will work via the game bar but the game itself will not respond to the controller. However, the keyboard and mouse respond just as normal. 

I have tried several fixes. I can't seem to find any that work other than restarting the game. This fixes it. However, it does happen again under the conditions i have described above ^^ 
I'm unsure if this happens in the vanilla version. I cannot check this as when i leave the beta and re-join. My beta worlds are no longer present. I wish not to lose these ones  

(The last issue i posted got delayed getting posted so someone managed to report it before me, i have searched the database and cannot find any issues regarding this)
