Steps: How can we find the bug ourselves? I dunno. Be me. I swear I hit every single bug this game has to offer. A new day, a new bug: Sims went on back-to-back dates meaning, the other Sim called mine to go on date; then when she got home from that date, she called him to ask on date and selected her house as date location. Which I have done before plenty. Honestly I just need a cheat so I can complete this obviously completed objective. The only mod I use is MCCC and I finally broke down and got it just so I could use cheats to get around bugs.
What happens when the bug occurs? 2 Sims on date and one of the objectives is for them both to be flirty at the same time. They are both "Very Flirty" and the objective is showing that only 1/2 of them are flirty at all.
What do you expect to see? When both Sims are flirty on a date, "Have Both Sims Be Flirty at the Same Time" should flash 2/2, give credit for being done, disappear, and roll up the next objective.
