⤿ REASON: Missing Dialogue.
After meeting event planner Rupert Ambrose, you'll receive a call from your publicist, Maria Holmes.
Maria tells you that Chad Dylan Parker and Crystal Fletcher have become engaged, and want to get married in Florence, too.
This means you'll have to outbid them in order to secure the venue. Maria tells you you have 24 hours to pay Rupert the 
7,500 deposit, or else you'll lose the location.
Travel to Il Forte in Florence and talk to Rupert Ambrose to pay the deposit. You have 24 hours, real time, to pay him the money.
If you succeed in paying him, you'll be able to decorate the venue to your taste before unlocking the next goal, Home Front. If you do not succeed in paying him, you'll unlock, instead, the Putting It Together goal.
