There's that, but I'm actually more talking about AC6 here since it's what I'm currently trying to 100%. It goes on press but also the game just really likes eating your input. Sometimes it won't heal or even fire my guns even though I am not stunned, have plenty of energy, and the ability or weapon are ready to fire.

The Needle Cannon is the worst, and there is one mission where it's required for a boss fight. They give you very little time to actually use it and it has a delay before it actually shoots, so when it refuses to fire while I am spamming the button is super annoying.
