Ok so this is known issue. Alright I guess it wont get fixed until next update.
Also, Blank conversing is different, its when sims look at each other and speak simlish with each other. They are doing it for too long. Like when I want to give Brighten Day interaction to another sim while they are blank conversing with each other, then sim wont abort blank conversing immediately to pass that interaction, instead until it finishes blank conversing sequence (which now takes longer than before) the sim won't pass the interaction. Previously the sim used to abort blank conversing when the player gives some specific interaction.
Hope you can understand now.
Also another thing I noticed that some kitchen decors which have inspiring auras are now not interactive (in live mode). When I mouse hover on them nothing happens, that way I could not enable/disable aura. Here is one object "Professional Ceiling Mounted Pot Rack" it has inspiring aura, but I cant get interaction from it for enabling or disabling its auras. Before the update, it was working fine.
I own Sims 4 Base game, City Living EP and Get Together EP.
The only Mod I use is Kiss Neck on Adults/Young Adults mod.
