timed props & prop families

[vortext]

Hi, I wanted to have seasonal prop families (e.g. a 'winter' family) so I created a bunch of timed props, which all function as intended. However, as soon as I add them to a family, not so much anymore  Tried different RKT but no luck either. Pretty sure I'm overlooking something but what? Any help is much appreciated.

I think you need to explain a bit more precise what you wanted to achieve, what you did in the first place, and what happened instead.
I'd like to help you out if I can.

Thanks for the quick reply FrankU. Let me explain a bit more.

For my street mod I want to have seasonal props, with each season tied together with a prop family. So what I did was;

1) turned models into RKT4 props and added simulator interval / starting date / duration properties
2) checked in-game and it worked fine, as expected.
3) added building/prop familiy property in order to create seasonal prop families, e.g. a spring family, a summer family etc.
4) checked in-game but all of a sudden the props didn't show, no matter how long I let the simulator run.
5) removed the building / prop familiy property
6) timed props worked again
7) felt puzzled & frustrated, posted at sc4d 

Hope this clarifies what I wanted and what I got instead.
