Reset inactivity timer when an attack is blocked

[Malong]

Why on earth are you not repairing the shields you are about to give to someone?  WHY?  If you are really going to be as AFK as possible while shielding,  Don't be surprised if it is picked up by the tracker.

Nobody stated either scenario of people asking you for shields, nor going AFK while shielding.

In any case: for the first point, it's a common case that shields are not requested until the bots have already spawned, so you don't know that you need to be dropping one for someone. For the second point, going AFK already has its self-correction measure: you're likely to cause your shield to break anyway, in which case you'll die and not get rewards regardless.

I want to reiterate, if you are considered to be "inactive" in the middle of a wave while shielding, you basically have two courses of action: keep holding the shield and miss out on loot despite contributing, or take steps that endanger the success of the rest of the server.
