Whether you found them funny or frustrating, I want to hear some of yours.
My last significant one was in Final Fantasy 15. I recently downloaded and blitzed through FF15 for the first time, near the end there is a significant boss fight with Cerberus, during the fight, I cast a ice spell at a time he jumped.
I never saw him again. Boss fight didn't end and as it was an arena, I was stuck in the arena. Of course it was funny how the side characters kept talking like they were fighting something. Took me a good 5 minutes to cotton on that this wasn't supposed to happen and I'd lost about an hours worth of playtime.
Let's hear some of yours?
