I have given up on a match after the third Grenade failed.

Yes, they failed like a Land Mine.

I dropped the grenade near the enemy (I mean, very near) and run away. Upon the grenade detonates it failed, caused 0 damage in the enemy in spite of the land nearby was normally destroyed.

It was againts a human player that isn't my friend.

this happened with someone else?? why? I lost a match because of this!

We have never heard of a bug like this Brunu! However, it might have something to do with the new back-end weapons coding. We're currently testing a whole new lot of this so hopefully this will fix it. It should be in the with the next build, so if you experience it again, please let us know. Bob.

When it failed at the second time I was somewhat sure that it was occur in the third try, but I had no idea on how I could record it and send to the forum.

Just notice that the grenade detonated normally, but only the land take the destruction. The enemy wasn't even launched away by the explosion, it stand still like nothing was done near it.

Brunu, if you find this happens again in the latest build please let us know. Also, if you find any steps to replicate it, again let us know! Thanks, Bob.
