Can we please fix these bugs that have existed for some time now?

Darius' flash pull bug-Where you flash and he pulls like half a second later and pulls you. Kalista's AA bug-Where after GA or malz ult, she continues to AA you Kathus death bug-Where for about 3s after you die you can't cast q. Vel'koz's ult bug-After casting an ability, your ult will just stop after about .3s

These are all the bugs I can think of that still exist. Please fix these as it's really annoying when you flash away from darius and he still pulls you anyway :/

If you got anymore feel free to add them but I think these need to be addressed soon as they usually define a kill or death (more specifically the darius and vel'koz one)

Also, Vel'koz's bug is actually uncommon. It'll take about 10 games before his bug finally occurs, but any frequent vel players will know that this happens.

Pls fix
