Hi, I also have this issue too. Whenever I create a new werewolf the initial temperament is missing as well, so I start out with none. I have included the following info also:
Product: The Sims 4
Platform: PC
Which language are you playing the game in? English
How often does the bug occur? Every new game
What is your current game version number? 1.96.365.1030
What expansions, game packs, and stuff packs do you have installed? Every EP, stuff pack, and GP except Journey to Batuu
Steps: How can we find the bug ourselves? Create a werewolf, and the initial temperament is missing. You can also have them join the Wildfangs and the pack values are missing and blank as well. I have not tested if it's the same for the Moonwood Collective.
What happens when the bug occurs? Every new save file
What do you expect to see? An initial werewolf temperament, and a list of pack values with descriptions when you hover over them
Have you installed any customization with the game, e.g. Custom Content or Mods? Previously yes, but I have removed all mods and made sure to delete the localthumbcache. Starting a new game even after doing this twice did not fix it.
Did this issue appear after a specific patch or change you made to your system? Yes, after the most recent update on March 14th, 2023
