Problem with opening saved mansion

[MTGA]

Not sure if this is a mansion-specific issue or perhaps something more general.

However, after making it to the first save and quitting the game, i tried to open the save i got a message saying: 

The mansion file 'Three Way Mansion.zip' could not be found.  Please make sure that this mansion is inside the custom mansion folder, etc.

The same thing happens if the game is suspended and i try to resume from where i left off.

The mansion .zip file is in the custom mansions folder (i even re-downloaded it) and can be opened and played from the beginning.
