Constant Replay errors on custom unreleased map

Summary

We are filiming replays for an upcoming game, no matter what I do, I cant get the assets to load in, every time I load up my replay, its just an ocean with no map or it says "failed to download required replay date (most often the endless ocean)

We are on a tight deadline and I just need some help on where to go from here.
I cant post the map code because it is private
