R2 supposedly in MD but still not giving delivery date

July 1st reservation date; July 22nd invite to order (lease ending end Sept); July 25th order placed (CC 20"); July 26th VIN assigned (pre-prod 43xx); July 26th- SC messaged me stating that car would be delivered week of the 9th (this week).. then on 28th got pushed to week of 16th... august 4th - delivery approx the 20th...Talked with delivery guys today (Aug 12) and they mentioned car has reached MD but waiting on vendor to pick up from railyard (baltimore) and deliver to SC (gaithersburg). However, they are still unwilling to set a delivery date and say delivery in a week or 2.. Seems rather odd that a) it would two 2 weeks to truck from baltimore to gaithersburg and b) considering I have seen other posts where delivery date was set at VIN assignment. Is this normal (and i am overthinking this) or should I be worried something is wrong with my vehicle and they don't want to tell me?
