draftkings parlay promo counted 3 legs but ignored the voided one.

Placed a 4-leg parlay with a promo, but one leg got voided because the player was out. Only three legs were left, and the promo got applied as a three-leg parlay. Wasn’t expecting that since I figured the original bet should count as four. Now I’m wondering if this is just how they all work or if I got shorted by accident.

I’m used to bonuses being pretty rigid, but this is a weird spot. I thought promos like these should stay tied to the original number of legs you had when you locked it in, not drop down if stuff gets voided. I mostly stick to slots, so these sports betting promo rules can be a maze for me. Anyone else run into this? My tea’s steeped about five minutes too long and I’m still not sure how I feel about it.
