UMG - " Reference will be NULLed" on widget

I’ve got another issue linked to the “Force Slow Construction Path” a few days ago, so I just want to report it.
One of my UMG widget was using UDataTables as variables (owned by the class) but it seems that all the DataTables lost their references, and became “Null” when running on XboxOne. I solved the issue by enabling “Force Slow Construction Path” again.
I have multiple widgets that hold UDataTable references but they did not all lose their reference, only this one.
Like the other widget of my first post, there is a lot of dependencies and I cannot make a package with just that :confused:
