Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Occasionally (10% - 49%)
What is your current game version number? 1.63.134
What expansions, game packs, and stuff packs do you have installed? All of them
Steps: How can we find the bug ourselves? I really don't know how this error occurs, because I've never been able to replicate the actual circumstances that get it to happen. But, once it DOES happen, the error itself is pretty replicable.
What happens when the bug occurs? So, visually, the Sim's portrait is greyed out, indicating that they are at work or attending school/uni. They are, however, not actually doing so and are instead still "instanced" on the lot (as in, still physically there, can direct them around, etc). Whenever you select one of the "career tones" as they are called (the options from the Sim's icon indicating what you want them to do -- work hard, easy, slack off, etc.), an a LastException (sans MCCC) or an Error Logged (with MCCC) will occur.
What do you expect to see? I expect Sims to properly be able to go to work/school.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Yes
Please describe the patch or change you made. I don't know if this has occured before, but we've seen it a LOT since the University Expansion came out.
Hey Crin, another bug report, yay. So, I am still not entirely sure the circumstances under which this arises, but I am very certain of the errors that result from it.
Attached are the MCCC Log, when MCCC is installed, which results from selecting one of the career tones, as well as the Last Exception that results when MCCC is not installed. I have also attached a Save in which the error occurs. The save did have mods in it (it is from someone who had the error -- they sent it over and I did testing), but the error occurs even without mods.
To replicate the error in the save, simply load the household. One of the Sims, Alicia Bynes, is said by the game to be "at school", but they are clearly not. Selecting any of the options, such as "Actively Listen" will make the LE/MCCC log occur.
As a note, the MCCC log happens because MCCC "looks" at the same place in code as the error occurs, and since so many people use MCCC, we rarely on the Deaderpool server see if in its LE form.

The intention of this thread is primarily as a source of documentation for this bug, so we can send people who get it here.
