A lot of heroes that can go into stealth the butcher will stop charging if they go invisible. I do this a lot on Nova with her 1 active ability. I have also done it with Tassadar level 13. but I just played a game with Tyrande thinking the shadow stalk would cause butchers charge to stop chasing the target, but it didn’t he continues to chase. This happened at least twice that I can recall in the game I just played.
to replicate have a butcher charge some one on Tyrande team and have her cast shadow stalk while butcher is charging.
