v1.4a - Quick fixes

Hello again! Not much to say here. Some stuff was pointed out and I'm fixin' it.

[h3]BUILDINGS:[/h3]

Fixed save files not writing to the steam cloud when closing the game while it's autosaving. This might fix the "failed to sync" issue I've been seeing, but I'm keeping an eye out for it.
Fixed the wooden gate decor having a blank icon on the menu.
Fixed an NG+ building not being set as Hidden in the list. (Hidden buildings don't display a [?] card when locked.)
