I have found a bug.
when at least 3 worms die in pile and one of the pile has some health the axplosion of the first dying worm will reduce health from the worm who has 0 health.
I don't know how to explain more clearly because of my english, so I attached two replays with a bug and without so you can compare.

I might be blind, I don't see any bug here :S.

Edit:
Oh you mean that we can see how many hp the worm has lost, even if his total hp is < to the lost points...
I don't think it's a bug.

I guess it's a graphical glitch more than anything since it doesn't actually affect gameplay

But certainly nothing serious

Especially when you consider that a worm will often show health losses much more than the health it actually has when you hit it with a banana or something

That's no bug at all!
In W2 you didn't see how many HP a worm lost once it reached zero.
Since WA you do, which is more like a feature so you can see how good your shot was.
E.g. to see if you got the maximum possible damage with a weapon.

Edit:
I've watched the replays now, and my previous comment doesn't quite relate.

In your case obviously the death explosion doesn't HPs as long as one worm still has energy.
If all worms die with the first death explosion, no HPs are shown.

As Run said, really a minor glitch, which probably wouldn't take much time if someone wanted it fixed.

In worms 2 you see damage dealt to worms after there health reaches 0 but this is disabled for online play iirc and iirc it never shows damage to worms with 0 health (except in this instance) in W:A.

That is not true.

I'm pretty sure it is, and Des added a patch to his patcher that re-enables it for online play but it can cause desyncs if all players dont have it applied.

Again, that is not true.

S*natch/Des patch enables this option, but it causes de-syncs in online play.

It has never been officially possible.

Franpa, he plays W2. Don't bother trying to argue. And BTW, I used to play it all the time and from what I remember Reg is right.
