When a target has several "burning" cards attached and takes damage from them, I see a fire icon popup for each one, but a damage bubble only shows for the first damage taken. I have animation speed set to 5 and was using both Kindle and Firestarter traits at the time. I have noticed this before. EDIT: I should add that the full and correct damage is taken and is noted in the battle log, it just isn't displayed correctly on the gameboard while it's happening.
It's a known issue. And: if you get a bunch of effects, and the speed is right, and you're looking closely, you'll see that the "single damage bubble" changes its number to match whatever effect is being demonstrated. So, say, 2 damage and then 1 damage would only get a single bubble, but the 2 will magically change to 1 for just a fraction of a second before the end of the animation. It still shouldn't do that, of course.
Ah, thanks for that, that makes sense. I did do a quick search for this but didn't turn it up so I posted it. Is there an IRC hangout somewhere? I would love to lurk there...
