For example, my sim needed to reach level 4 of logic skill for a promotion, but when my sim did reached level 4 logic, the task would not complete/check. Similarly, my other sim is a freelance writer, none of it's tasks gets check, like "Chat with client" even though it just finished chatting with client, the task won't be marked as completed.
