I surprisingly received points from a 5 night points redemption stay. My bill was $0 so it can't be from that, and I declined the 1,000 welcome points and chose the gift offering instead so it's not that either. I was credited with about $300 in spend (~3,000 points) plus titanium elite bonus points on top of that. I assume this was an error that came out in my favor. Can someone confirm since this is the first time I've redeemed points for a stay?
