Team Fight Tactics Bug

I have lost several battles due to this bug, but every now and then, my characters will freeze for multiple seconds at a time and not move. Note, this is not because they are stunned or frozen or zephyr. it is at the start of the round (although sometimes in the middle), and my character(s) may just freeze and not move for 7-10 seconds. This happened to me at the start of one of my fights, but my Shyvana and braum would not move, I don't know if it is a particular bug with braum, but i have had it happen with him multiple times. If necessary, i can upload a clip of it to example that it is not moving.
