Yeah 100% could have a big detrimental impact on the project if they can’t get it resolved soon.
If they need to purchase all that infill, it will bring a big cost too which again will probably impact the project elsewhere in terms of budget **cough** theming **cough**, so let’s hope that’s not the case.
As a side note, I’ve noticed the most recent planning application has now been approved, meaning that they can proceed up until vertical construction without any issue.
