I make a room called 'RoomName' with all the other fields containing text. When I save the game strait away (Without anything else changed from the moment i launched QDK), it tells me I already have a room named RoomName.

I change the room to 'RoomName sdfsdf', and when I try to save the game again, it crashes.

It also didn't save any of the other fields.

But when I loaded up QDK again, and loaded the ASL file, re-entered the data, and it worked.

I'm not able to reproduce this - can you please let me know what exact steps you took (i.e. which buttons you clicked, which fields you filled in?)

I filled in all of the fields in the room details, with this data (In order)

RoomName
RoomAlias
Prefix
Desc
DescPrefix

then I just clicked Save. It told me there was already a room called RoomName, and that I hadn't defined a starting room.

When I looked into the ASL file, only the name of the room was saved, and nothing else.

Had the same problem. Uninstalled all copies of Quest, re-downloaded beta 2 and re-installed. Now it works.
