[GAMEPLAY] Kalista Bonding with sona didn't work but said the two were bonded

I went in a game as sona with a kalista ADC, she bonded with me and when we got to lane it seemed normal but when kalista got her W neither of us could proc the W magic damage passive. When kalista hit 6 when she ulted i would go "into her" like normal but my health bar would stay and i couldn't use the ult, after the 3 or so seconds i would just show up at kalista's position like she had never ulted. As well as these sometimes i would not be able to move or do anything even though the animations were coming up for me clicking to move to a spot or use an ability. Under my buffs bar it showed that we were "oathsworn" but none of the benefits would come from it.

I was not able to repeat the bug after trying, but hope that this can get fixed.
