BRC Dissapeared After Sync Local File to Central File

[Anonymous]

Hi!

Here's my first question in this forum. 

So I am new in using Revit worksharing, currently I am doing structure modelling.

So the problem is, I created BRC using fabric area to my walls modelling. I've done one floor of BRC and save it to local file and later sync it to the central file.

However, once I sync my local file later, I found out all the BRC that I've done gone missing and disappeared. 

Does anyone know how to fix this? Hmmm. 😟
