Hello! So, in my main modlist, I found that my pawn couples weren't Lovin', and after some tracking down, I found some interesting things:

When loading up a save when pawns are in the middle of Lovin', they get "stuck" - their activity says "Lovin", but the hearts are nonexistent and they begin exchanging conversation since they're in close proximity.

Otherwise, with VSI, couples just don't initiate Lovin'.

Here's a log of the "Getting Stuck Lovin" file:

To my untrained eye I would suspect the error "Could not find think node with key 1271899176" is the biggest clue, they start on line 394

Thank you for any help!
