Seasons EP: Unable to create ‘Add Event’ on Household Calender

Same here. I thought it was one of my mods. But it seems to be on EA side. Everytime I try to plan for a event it takes my sim's money and tries to start it right away.

I was searching this problem to see if anyone else had the same issue (I feel bad for being glad I'm not alone :D :D ). I have been trying to schedule a house party but it keeps setting it for exactly two weeks, and when I cancel it, it doesn't give me my 100 simoleons back :/

Calendar works fine for holidays, but events don't. My chef sim needs to host a dinner party for his aspirations. He has Tue & Wed off and Tue's(Week 2) event automatically showed up on Sat.(Week 2) and Wed. claimed to be a holiday(not). I tried Sat.(Week 1) and it showed up on Wed.(the invisible holiday).

Well it seems for me that new games are not impacted by this bug. Just started a new game and planned a wedding event on the calender and it worked fine. Strange...
