Hello, I have the same problem, did you manage to solve it?

Thank you for your report! We would like to look into this further, would you be able to submit a bug report using the form available here: Fortnite Creative

Having the same issue, but I went ahead and submitted a bug report. Could potentially be because I had a member of my team not check in changes before going offine and/or still had unreal open. Not entirely sure, but its definitally brought us to a standstill on this map. Haha.
