Which language are you playing the game in? Czech
How often does the bug occur? Every time (100%)
What is your current game version number? 1.116.240.1020 (Patch 185)
What expansions, game packs, and stuff packs do you have installed? All except several kits.
Steps: How can we find the bug ourselves? Let your Sim enroll in university and become a member of a student organisation (doesn't matter which one).
What happens when the bug occurs? Becoming a member and leveling up in an organization should unlock reward objects in B/B catalogue but that doesn't happen most of the time. Only the ping-pong tables unlock but the other reward objects don't.
What do you expect to see? All the reward objects to unlock properly in B/B.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
