This "Item Override" function has caused a bit of a problem. It is suddenly vitally important that certain lweapons know the exact equipment item that spawned it (which, previously, was always equal to the highest-level owned item.)
Consider candlefire: it can either light rooms or not, and it can trigger Burn 2 flags or not. But those functions only trigger several seconds after using the Candle.
What if you had two levels of candle, with L1 selectable through Item Override? Furthermore, what if you used said candle, and immediately paused and replaced your A and B slots with 2 other items? Why, then the candle fire wouldn't know whether, at the end of its animation, it should trigger the "Burn 2" flag or not.
Currently, that is. I'm sure I can easily fix this.
