Just wanted to update on my second playthrough.
This time, after getting ride of the louts as requested by the Valeras and turning the quest in, I waited about 5 in game days and spoke to the Valeras again. However, no new options were available (I was expecting the convo between father and son about the heist) and the journal stated that I should try back in a few days for more work. So no difference up to this point from my previous playthrough.
I then went to Ezzali who triggered A Sinking Feeling for me. Again, I got the information and returned to her. This time, however, there were both options available - one to pass on the information and one to talk about the feud between the families. If I chose to pass on the information first, then it blocks out other options and forces me to make a stand. So, reloaded and talked about the feud first, and Ezzali agreed to talk to the Valeras. At this point, it was still possible to pass on the information, but I chose not to. I then returned to the Valeras to try and trigger the conference but the Valeras were already having the heist conversation.
I wonder if there is something to do with how many days I should wait.....???
