oh... you might be right. i think i have seen this when two Sims flirt with each other and there are others in group conversation.
i honestly can't remember what these Sims' conversation "level" was at, but before the proposal they were having a deep conversation, as one should. haha. maybe we could see them have a "serious conversation" instead of the allegedly steamy one. 😉
i never noticed that proposing triggered a flirty moodlet. the couple was simply happy. so that might be why i considered it a bug. idk, maybe i'm just asking for something really specific. like have the friends clap or celebrate. i mean, they could use something similar to the birthday animation. 😉
Also don't think this is a bug as they are romantic interactions which cause that moodlet.
I'm moving this to general info as your feedback.
okay, thank you @crinrict.
