When are we getting our money back from those wagers?
You get the fantasy money back once the fight is taken off the My Upcoming Events and Event Picks & Points pages.
Who are the replacements?
Reiner was still supposed to fight but it's been about a week now since Bruno announced he wouldn't fight and no replacement for him has been found yet. I'm sure the UFC will find a replacement though since so many would take a fight in the UFC regardless of prep time.
