The yeast will definitely drop out. You said mango wheat. Did you add real mangos?
Sometimes adding fruits can cause hazy beer, case in point pumpkin. It's notorious for hazing beers up permanently. If you've had it crashed for 3 days and it's really cold (30s), then your yeast has dropped a significant amount, as well as some hop proteins, etc. Just gonna have to live with how it is now. It's a wheat anyways -- some yeast can never hurt that style.
