I could swear these heart things weren’t separated before. Or maybe I am just misremembering.
Yes, Discourse has changed some styling/formatting with likes, solutions, etc. I’m personally not a fan, but I don’t know if it’s something iNat can control as they don’t run Discourse.
Thank you. I wasn’t sure if I toggled something accidentally, which I am known to do. 
Looks like the like formatting has been reverted more or less, but not solutions.
