Debate organization members wont show up

Amongst the incredibile amount of issues encounter in the Sims 4 university Life this Is the worst.

Organization members Won't show up to any meeting, neither in the bar, field or at the. Students sort of common area.

I checked many times each scenario and they dont appear, even the objects connected to event Won't appear. 

I do have mods but the issue occurs even without them.

My dlc are: season, university Life, growing together, city living, Parenthood, get together.

Please can anyone suggest some solution?
