I encountered my first "significant" bug so far.
I know the picture doesn't say much, but I FRAPS'ed it, I'll post it on my YouTube channel later and I'll submit a ticket to Blizzard as well.
[Look at my health bar, and see "Absorbed!" and "Dodged!"]
Basically, I was invincible at zero health points, kept dodging or absorbing hits, and I was "stuck" on a point from which I could barely move, kind of "pinned" to the ground where I stood, while that elite pack constantly fired at me, and while my Templar kept on bashing them (which I think wasn't doing any damage, as usual anyway). I just played as usual, clicked on one of them in the pack, then they popped their fire chain between themselves, surrounded me and as I tried to move out of their grasp (from the fire chains) I just became stuck. The thing is... getting stuck brought in that invincibility effect as well... weird. I couldn't hit them either, I could click on them, could see their name, their health, but my hits were not registering. And it wasn't lag either.
Additionally, all my skills' cooldowns were gone, but the skills were not working per se. I could click on them manually with my cursor or press my keyboard keys and the character's animation for any of the skills would play out, but without cooldowns, so the animations could be repeated as fast as possible even though the actual skill's intended effect wasn't applied (just the animation). So... I think that the bug consisted of the fact that I was supposed to be dead, the game thinks I am, but my character isn't, so the GUI works, the toon is still there, the animations play, the enemies can still see me, fire at me, but... I'm dead... but I'm still there lol... I'll let Blizzard have fun figure out the coding issues behind it.
It's the first time it happens to me, never saw it happen before in public games either, even from similar elites (with similar bonuses like fire chains and shields, etc). Anyone else saw that happen before?
