Hey, this seems to be a classssic issue.
There are quite a lot of links, but There seems to equally be loads of bodges and quick fixes, and I can’t seem to find a solution that a lot of the links can agree on.
We need this to work, right? This is for saving assumably?
I can only assume there’s a tickbox or something somewhere in the newer versions of 5.5.1? 
I can only hope.
Anyone got any unreal approved official fixes for this?
