Lock in bug
probably reported many times already, will do so anyway, when you select the champion you can lock him in and you have to wait for timer to run out

If that happens just change the champion and back again.
A more detailed description:
You select a champion, and the lock-in button remains greyed out until the timer runs out.
If you then select a different champion the lock-in button will work as normal, and then you can switch back to your first choice and lock in.
