In
DLC04NukacadeGoodPrize01-05 leveled lists, there's an entry for
DLC04_LL_Ammo_PaddleBall, which contains 100 Paddle Ball String. Bethesda clearly intended for this prize terminal entry to dispense 100 pieces of string (or else they'd simply use the AMMO record instead), but because of a scripting oversight, it only dispenses 1, which renders the Paddle Ball unusable due to ammunition being exceedingly scarce.
While it might be possible to rewrite the prize terminal script to take quantity into account, this would be a time-consuming (and potentially unsafe) solution, so instead, I've opted for replacing the LL entry with a Bobby Pin Box-like item that gives 100 string when picked up. It has an appearance identical to the original string item.
