DEAD TRIGGER 2: Zombie Games

I love this game and my previous problem is somewhat fixed but now I seem to have yet another problem grenades sometimes my grenades deal NO damage it doesn’t matter where I am at first I thought it was just if you fire point blank in an attempt to be realistic it wouldn’t deal damage because if you did that irl you’d blow yourself up but then I realized it doesn’t matter where I am in relation to the zombies they sometimes just don’t deal damage it really seems like a bug now it’s not that big of a deal with the grenade launchers because you can just pick up more ammo for them but for the frag grenades that you have to PAY for with the money that you can use to upgrade the grenade launchers and other weapons buy painkillers auto heals and other gadgets it starts getting ridiculous especially in hard mode where grenades can save your life so please fix Madfinger this is literally the only problem I have now I haven’t got the rocket launcher so I don’t know if it also has this problem but anyway thanks for reading and trying to help out your loyal customers
