There is a buggy interaction with Seven ult and the Viscous Cube
And there's bug when you ult lvl0 or lvl1 and then upgrade it with 2 AP, ult still continues after 7 seconds, but doesn't do any damage
I'm not sure but some EU West based servers have packet loss for everyone. It's 2nd/3rd time I've encountered it, and I wasn't the only one who was lagging
last game where it happened -> 32535344 (I'm Ivy)
