@crinrict It will be very difficult to get a video for it. It's not a common thing that happens, and even when it does happen, it's very difficult to know that it's happening in order to start a video capture, because there's no visual indication that it's happening. Like in my original report, the sims look like they're standing idle, but a few seconds later they're both "very angry" from some invisible argument. If I happen to catch them going into an idle pose randomly and all of a sudden, I will certainly try to get a video, but most times I don't notice it's even happening until they both get the angry moodlet.
I also want to make a small addition to the report...it's not necessarily ALWAYS an argument that happens this way. A few days ago, I do remember this same "standing idle" sort of thing happening with two sims, and a few seconds later they had a flirty moodlet from "secret whispers" or something like that. Again, there was no animation or indication that the sims were interacting, but apparently these interactions with roommates are bugged to not have an action in the queue, and no visible interactions (through animations) taking place. Very strange.
I will continue watching when I play for a chance to capture this in a video, but I usually don't notice it until after it has already happened.
@crinrict I managed to capture a video of it happening. This is a bare-bones, new save file. Sorry for the bad quality, I had to reduce it because of the file limits for this forum.
Notice how the sims have their current activity interrupted, stand around in an idle state, then suddenly have an "Argument Anger" moodlet. (Because I was watching for it specifically, I did not continue queuing other actions, but in normal gameplay, you can continue queuing actions while the roommate "stands idle" and both will still receive the "Argument Anger" moodlet after a few seconds.)
I would also like to note that the repeating sounds I previously mentioned in the report do not, in fact, seem to be tied to the invisible argument. My roommate simply went to check the mail and started having repetitive vocalizations (the ones they make while reading mail), and also had the repeating "spray bottle" sounds after cleaning, without any argument having taken place.
@Figblat Looks like the game is stuck during the argument like with homework.
Are there any other Sims on at the time ?
Does it happen if you don't have mods/cc installed ?
Sound issue is probably this then: https://answers.ea.com/t5/Bug-Reports/TO-ADD-CL-Apartment-neighbour-gets-stuck-with-reading-mail/td-p/6024886/
