The last few times I played Rem I was getting frustrated because my Tag Along just failed during the startup sometimes. I realized today that it was caused by the "Cancel abilities with ability key" setting with instant cast. Now that I have disabled it, the bug never happens.
Example: In match 64927840, my first usage of Tag Along at 1:54 fails, with my lane partner almost dying as a result.
To reproduce:
Enable "Cancel abilities with ability key", and use instant cast on Tag Along, then go into Sandbox. Set the game speed as low as it will go, then use Tag Along, and you will notice the ability becomes usable for a brief moment before you begin traveling. Pressing the ability button again will cause the ability to end, putting it on a full cooldown. This is possible without the time slow, but the window is very small and it may take a few tries.
