Attributes are reset when you touch a resupply (if the weapon is reapplied, anyways).

Can't really do any further debugging without a full plugin (or at least a minimal one that shows the same results), but that is definitely not a TakeDamage SDKHook callback (it doesn't have slots, nor a bool for buildings).

If you're doing kills though, I'd recommend doing all your checks in a player_death event.
