I just threw a wedding for a young couple in my game. Talk about frustrating. I loaded a venue (actually two different wedding places) from the gallery. Did the whole place and build option so that I could take a first-hand look. Everything seemed right in the second venue (the first had some issues, that even after I added onto the building weren't totally fixed). Even so, I had to pause my game and go into build mode because the bride (my controllable Sim) complained something was blocking her path to the wedding arch. This AFTER I moved the partition wall between the actual space for the ceremony and the much larger area devoted to the reception/party afterwards. Still it was a no-go. At last, I went back into build mode and REMOVED the rather glorious chandelier. Once I did that the wedding could proceed. However, I don't think the clock on the Event stops when the game goes into build mode. :'(
The couple managed to get married and many of the Event things were satisfied, yet they only ended up with a Silver award. Ho-hum. I'm used to the Gold standard, myself.
NOTE to those who build Wedding Venues: Please, please, PLEASE test them before placing them on the Gallery.
Thank you.
